West Ham United boss Sam Allardyce says the Premier League's new financial controls will prevent them from signing Liverpool striker Andy Carroll.

Allardyce admits he wants to keep Carroll.

"The hardest thing is the overall package and making sure it is sustainable," said Allardyce. "I point to financial restrictions being implemented next season that will blow the whole deal in one go.

"Someone will have a bigger budget than us probably but this is what is going to happen.

"In one fell swoop the financial restrictions mean we won't be able to sign Andy Carroll from Liverpool because it is too expensive, even if we wanted him, which we do."
