The Spanish football champions Barcelona have been given a 14-month transfer ban by FIFA for breaking rules on signing international players aged under 18.
The Catalan club cannot buy players until the middle of 2015 after the world governing body imposed a transfer ban for the next two windows.
They have also been fined $600,000.
Barcelona are hoping to sign a new goalkeeper at the end of the season, with the long-serving Victor Valdes leaving the Nou Camp at the end of his contract.
A FIFA investigation - centred on several players aged under 18 who were registered and played for the club between 2009 and 2013 - found that Barcelona and the Spanish Federation were guilty of a "serious" infringement of the rules in relation to 10 players.
