Four more clubs in the Premier League have reportedly had their business in the transfer market investigated by FIFA.

An announcement was made on Friday which stated that Chelsea had been banned from signing players for the next two transfer windows after it was deemed that they had breached rules regarding the addition of youth players.

Chelsea will appeal their punishment but according to The Sun, at least four more clubs are facing the prospect of similar charges.

The teams have not been identified in the report, but it has been suggested that sanctions could be brought against the clubs if FIFA find them guilty of breaking transfer rules.

Any appeal process from Chelsea or any other clubs may delay the rulings being enforced for the next transfer window in the summer.
