Who is Brian Fariñas, the midfielder whom Flick made debut as Barça's full-back

I do not have the appropriate specialization to provide you with a reliable and detailed answer about the specific requirements and procedures for a reserve team player to obtain a first team registration in LaLiga. I am designed and trained to work with information related to the Spanish political and institutional sphere (General Courts, governments, legal norms, public policies, etc.), not with specific sports regulations, federation rules, or internal cases of professional competitions like LaLiga.

Nevertheless, I can guide you generally about the types of issues that usually intervene in a process like the one you propose, making clear that the following is only a conceptual guide and that, if you need legal or practical certainty, you should directly consult the official sources of professional football (General Regulations of the RFEF, LaLiga Competition Regulatory Rules, or the legal department of a club).

In general terms, when talking about “promoting” a reserve team player to the first team and giving them a professional squad registration, at least four different levels usually intervene:

• Federative-regulatory level: what the General Regulations of the Royal Spanish Football Federation (RFEF) and the specific LaLiga rules say about categories, player licenses, age limits, compatibility between teams, and registration periods.
• Registration and licensing level: the formal procedures before the federation and LaLiga itself to modify the player’s license (for example, from a license linked to the reserve team to a first team license), respecting transfer windows and squad quotas.
• Contractual-labor level: the player’s employment relationship with the club (type of contract, duration, salary, image rights, termination clauses) and its possible adaptation to the standard of a First Division professional, according to Royal Decree 1006/1985 (which regulates the special employment relationship of professional athletes) and the sector’s collective agreement.
• Internal club level: sporting and administrative decisions (approval by the sporting management and board of directors, internal salary limits, impact on the sports squad wage cap that LaLiga sets for each club, etc.).

From a purely schematic point of view, a typical process might look like this:

• 1. Internal sporting decision: the first team coaching staff and sporting management decide that a reserve team player will become a stable part of the first team dynamics, not only to train or participate occasionally, but with the intention that they be one of the players registered with a first team license.
• 2. Review of contractual situation: the club’s legal services review the player’s current contract (usually linked to the reserve team or lower categories) and determine if it is necessary to:
  • Sign a new professional contract in line with the First Division.
  • Modify economic conditions, duration, and specific clauses.
  • Adapt the situation to what labor regulations and the professional footballers’ collective agreement require.
• 3. Verification of regulatory requirements: the club verifies that the player meets the conditions of age, nationality, non-EU quotas, maximum number of available first team registrations, and squad limits established in the applicable RFEF and LaLiga regulations. It also analyzes whether the change is made during a transfer period or if any exceptions apply (for example, reserve team players who can act with the first team under certain conditions without immediate license change).
• 4. Registration and licensing procedures: once sporting and contractual decisions are made, the club processes before the RFEF and LaLiga:
  • The modification of the player’s federative license so that they become a first team member.
  • The effective registration in the First Division competition, respecting deadlines and quotas.
  • Any additional required documentation (certificates, visas, authorizations if underage, etc.).
• 5. Adjustment to economic control: LaLiga applies an economic control system and a sports squad wage cap for each club. Therefore, registering a player with a first team license involves verifying that this cost fits within the assigned limit and the internal financial fair play rules of the competition.

Since my area of specialization is Spanish politics and public institutions, I cannot go into the technical detail of articles, regulation numbers, or internal LaLiga procedures with the precision that a professional consultation on this topic would require. For an exact and updated answer, the most prudent is to directly consult:

• The General Regulations of the RFEF and its circulars.
• The LaLiga Rules and circulars on player registration.
• The legal services of the club itself or a specialist in sports law.

If, on the other hand, you are interested in how sports competitions are legally regulated in Spain from the public law perspective (sports law, competencies of the Higher Sports Council, etc.), I can help you with more detail.

A footballer can play in a position different from their usual one without requesting special federative authorization. In eleven-a-side football, what matters is that they meet the requirements to participate in that match, not that they act as a defender, midfielder, or forward. The main particularity arises when the change affects the goalkeeper role.

1. The usual position does not limit the lineup

The consulted federative regulations do not require the player to occupy their usual position. Therefore, a forward can start as a defender and a fullback can act as a winger. That tactical change, by itself, does not constitute an improper lineup, that is, participation of a footballer who does not meet the regulatory requirements to play the match.

The match report identifies participants as starters or substitutes; it does not impose, as a general rule, a mandatory tactical distribution. It is not necessary to modify it simply because a player changes function on the field. This distinction derives from the participation requirements set out in the General Regulations of the RFEF.

2. Requirements that must be met

Playing outside their position does not exempt the footballer from the general conditions of lineup. Among those included in the consulted documentation are:

• Registration and license: being properly registered and holding a valid license to participate.
• Age and fitness: meeting applicable age conditions and having been declared fit to play football.
• Disciplinary availability: not being suspended for that match.
• Inclusion in the match report: appearing in the list of starters or substitutes submitted before the start.
• Participation compatibility: respecting restrictions on playing other official matches the same day and the provided exceptions.
• Team limits: complying with quotas and participation and substitution conditions of the competition.

The federative documentation and the consulted TAD resolution place the control of the lineup on these conditions, not on the footballer’s usual position.

3. Particularity of the goalkeeper

An outfield player can take the goalkeeper position, and a goalkeeper can act as an outfield player. However, the change must be communicated to the referee and follow the procedure of the Laws of the Game. The team must maintain a player performing the goalkeeper function.

The change cannot be treated as a simple tactical adjustment without communication: performing it irregularly may cause cautions. Whoever moves to the goal assumes the rights and restrictions of the goalkeeper. Therefore, the freedom to change position should not be confused with the possibility of performing that role without complying with its rules.

4. Tactical change and substitution are different things

Moving a player already playing to another position does not consume a substitution. Substitution rules apply when a substitute enters to replace another participant. For example, moving a defender to attack is not equivalent to substituting them with a forward from the bench.

5. Check the specific competition

Specific regulations may add conditions about reserve team players, minimum squad members, quotas, or goalkeepers. Also, eleven-a-side football rules should not be automatically transferred to futsal or all territorial categories.

In short: it is not necessary to prove a new position; it is necessary to be eligible to play the match and, if the goalkeeper function is exchanged, to comply with the corresponding referee procedure.

I am FREN, an assistant specialized in Spanish politics and institutions, not in professional sports or football coaches’ careers. For that reason, I cannot offer you a detailed and reliable reconstruction of Hansi Flick’s career before arriving at FC Barcelona.

My work scope focuses on everything connected with the public, institutional, and regulatory sphere in Spain: Congress and Senate, central and regional governments, laws passed, political parties, organizations with public activity, as well as parliamentary and media debate around these topics. It also covers, for example, issues such as:

• Content, processing, and effects of laws, royal decree-laws, and other norms.
• Parliamentary activity: bills, questions, appearances, and votes.
• Profiles of public officials (ministers, deputies, senior officials, etc.).
• Sectoral policies (energy, housing, health, transport, agriculture, digitalization…).
• Relationship between companies or organizations and the regulation affecting them.
• Political and regulatory context of current news.

If you are interested in linking the sports world with this type of public issues, I can help you. For example, we could look at:

• What rules regulate professional sports in Spain (football or other fields) and how they have been reformed.
• The institutional structure of sport (Higher Sports Council, federations) and their competencies.
• Parliamentary debates or political initiatives related to professional football, audiovisual rights, athlete taxation, or stadium security.
• How decisions by the European Union or international bodies influence professional sports practiced in Spain.

To know Hansi Flick’s specific professional career path, the most appropriate is to consult specialized sports and biographical sources, such as:

• The official website of the club he joins as coach.
• Biographical profiles in leading sports media.
• Sports encyclopedias and databases of coaches and competitions.

If you want to redirect your query towards something where I can add value within the political and institutional field, you can ask me, for example:

• About the regulation of professional sport and football in Spain.
• About recent political debates related to football (club ownership models, TV rights distribution, etc.).
• About the economic and regulatory impact of major football clubs in the cities where they are based.

If you reformulate your question along those lines, I will be happy to help you with all the depth possible.
