Liverpool boss Rafael Benitez wants Fifa to pay compensation for Djibril Cisse's injury while on World Cup duty with France, warning football's governing body that coaches could start withholding their players.
Cisse, 24, fractured his right tibia in a friendly against China last week and is out until at least November, denying him a move back to France with either Marseille or Lyon.
A £8 million return to France - two years after he arrived at Anfield from Auxerre - would have given Benitez spending power to build his squad after finishing third in their last Premiership campaign.
"I believe Fifa or the national associations should pay the clubs in these situations," said Benitez. "Fifa is a very wealthy organisation and they make a lot of money from the World Cup. They should insure the value of the players they want to participate.
"If they're not prepared to pay for this, okay, maybe the clubs should say the players can't play."
Fifa and Uefa have clashed with the G14 elite clubs - which includes Manchester United, Arsenal and Liverpool - over player compensation.
Belgian club Charleroi, with the backing of G14, are suing Fifa after one of their players, Abdelmajid Oulmers, returned from national team duty with Morocco in November 2004 suffering an injury that kept him out of action for over six months.
