In football, how soon after signing a player may he play for his new squad? Liverpool are in the middle of signing Mario Balotelli from Milan in the Italian Serie A. It is reported, that if the deal goes through, he could be available to play this upcoming Monday (4 days).
Presumably different leagues have different protocols, and if that's the case then the English Premier League could be focus since that is to be his destination if the transfer does go through.
Is a recently transferred player able to play "instantly" for his new squad? Or is there a period of time before the player may start a game?
