Injury crises expose how little the transfer rules let clubs react

Key takeaways

• A long absence in mid-season is first a registration problem for the club, and only later a transfer problem.
• Outside the two registration periods, clubs can usually add only players who are already free agents, and only where the national rules allow it.
• Squad lists for UEFA competitions are fixed for long stretches of the season, so a replacement signed domestically may still be unable to play in Europe.
• An injured player's contract stays fully in force, so the club keeps paying the wage while also looking for cover.

A serious mid-season absence is decided by rules set in the summer

The Guardian reports that Paris Saint-Germain will be without three players after their Champions League win over Barcelona. One of them, Khvicha Kvaratskhelia, needs surgery, and the other two are expected to miss several weeks. The paper does not say how long the longest absence will be, and this article does not guess.

What the episode shows is structural. Supporters often expect a wealthy club that loses an important player to go out and sign another. The transfer system is built to stop that from happening quickly. Registration windows, competition squad lists and the protection football's regulations give to contracted players all work in the same direction. The squad a club registered at the end of the summer window is, with few exceptions, the squad it has until the next window opens. In October, a club's real options are its existing players, its academy, and a small number of narrow exceptions.

The point applies to almost every elite club in Europe. PSG is simply the latest example.

The registration window closes the most obvious route

FIFA's Regulations on the Status and Transfer of Players say a professional can only be registered during one of the two registration periods that each national association sets every season. In the major European leagues, one runs through the summer and a shorter one runs in the middle of the season, usually in January. Outside those periods, a club cannot register a player bought from another club, however much it is willing to pay.

That rule matters more than the size of the transfer budget. A club can agree a fee with another club in October, but the player cannot be registered or play until the next window opens. Clubs generally avoid striking deals that early in any case. Prices go up when the selling club knows the buyer is desperate, and plans can change before the deal can be completed.

The FIFA regulations do allow one important exception. A professional whose contract ended before the close of the previous window may, subject to the national association's rules, be registered outside the window. In practice this means unattached free agents. The pool is small and uneven. Players who are good enough for a club competing at the top of the Champions League are rarely left without a club once the summer is over. Those who are tend to be without one for a reason, such as fitness, age or contract demands, that makes them a poor fit for an elite squad.

The French league's regulations have also provided for a so-called medical joker. This mechanism lets a club register a replacement when a player is ruled out for a long period, under conditions the league sets. Those conditions are narrow and concern how long the absence must be and who the replacement can be. It is not known whether PSG would qualify in this case or would want to use it. The existence of the mechanism makes the same point: leagues treat a mid-season signing as an exception that has to be justified, not a normal option.

Competition squad lists freeze the roster a second time

Domestic registration is only the first gate. UEFA runs its own registration system for the Champions League. Each club submits a squad list before the competition starts, with a limit on total numbers and a set of places reserved for locally trained players. Separately, clubs can register youth players who meet age and club-training criteria.

Once the list has been submitted, changes are only allowed at fixed points, mainly a registration period ahead of the knockout rounds. Even then, the number of new players a club can add is capped. The exception for emergencies has traditionally covered goalkeepers, not outfield players. Losing an outfield player during the league phase therefore gives the club no general right to bring in someone new for Europe.

This produces an outcome that surprises many people. Suppose a club does find a free agent and registers him domestically through one of the exceptions. He might be able to play league matches but still not be eligible in the Champions League until the next UEFA registration point. For a club whose season is judged largely on Europe, that replacement solves only half the problem.

The locally trained quota adds a further limit. A club that has used its general places on expensive signings may find that its only open slots are the ones reserved for homegrown players. That pushes the choice of cover towards academy graduates or players with the right training history, not the best player available on the market.

The injured player's contract stays fully in force

The third mechanism is the employment contract itself. Under FIFA's regulations and national labour law, a club cannot end a player's contract because he is injured. The contract runs as normal. The player stays registered and keeps being paid his wage, and his place on any squad list is unaffected unless the competition's rules allow it to be released.

This has two consequences for squad building. The first is financial. A player who cannot play still counts towards the wage bill, so any replacement is an extra cost, not a swap. Clubs subject to cost-control rules, whether a domestic regulator or UEFA's squad-cost framework, must fit that extra spending within limits that were set with a full squad in mind. Insurance may cover part of the wage of a long-term injured player, but what the policy covers and how much is paid out are private matters. Nothing has been reported about any arrangement in this case.

The second consequence concerns the player's own position. Because the contract runs regardless of injury, a long absence does not by itself change the player's value or the club's rights over him. Any effect on future transfer value or renewal talks would come from the market, not from the contract. How that might apply here is not known and is not discussed.

Together, these three mechanisms mean that the depth a club decides to carry, and how it uses its registration places, matter more than any money it might spend once the season is under way.

Clubs can plan around absences, so the rules are not the real constraint

The strongest objection is that none of this is a surprise. Elite clubs know long absences will happen every season and build their squads accordingly. A club at the top of European football typically has more than one capable player for every position, plus academy players ready to step up. On this view, the rules do not leave a club exposed. Weak planning does. A club that relies on a single irreplaceable player has made a squad-building choice, and the window system only reveals it.

There is a fairness argument as well. The windows were designed partly to stop the richest clubs turning every setback into a chance to sign a rival's player in mid-season. Without them, an injury at a well-funded club could simply become a reason to raid a smaller club's squad at the time it would hurt most. Seen this way, the limits on reacting are the point of the system, because they protect competitive balance and the stability of other clubs' squads.

The rules are also less rigid than they look. The January window is never far away. Free agents can be registered under national rules. Mechanisms such as the medical joker exist in some leagues. UEFA allows changes to squad lists ahead of the knockout stage. A club that suffers a long absence in October has to cope for a limited time with what it already has, not for a whole season. Coaches can also adjust tactics and change the shape of the team. Many clubs have found that they can absorb an absence through how they play rather than through who they sign.

This case deserves to be taken seriously. It changes the argument from "the rules prevent a response" to "the rules delay a response and reward planning". That is a narrower claim, but it is still a real one.

Evidence that would change this conclusion

Several developments would weaken the argument that mid-season injuries leave clubs relying on their summer squads.

The first would be how the medical joker, or any similar mechanism, is used in practice. If French clubs regularly used it to sign players good enough to play regular minutes, the domestic route would be more open than this article suggests. Information on how often such registrations are approved, and for what kind of player, would settle the point.

The second would be any change to UEFA's registration rules. A general exception for long-term injuries to outfield players, or more freedom to amend squad lists during the league phase, would remove the second freeze described above. No such change is known to be planned.

The third would be what PSG and comparable clubs actually do over the next registration period. If clubs in this position routinely sign directly in January to cover long absences, that would support the view that the window delays a response rather than stopping it. If they mostly rely on players already in the squad, that would support the argument made here.

Finally, more transparency on how insurance and cost-control rules treat the wages of injured players would show how much financial room a club really has. If insured wages could be excluded from the costs counted under the rules, the financial side of the argument would be much weaker.
