West Ham United have made a complaint to the Premier League over comments made by Fulham head coach Rene Meulensteen about Ravel Morrison, according to Sky sources.
Speaking on Tuesday night after the FA Cup replay against Norwich, Meulensteen admitted that Fulham had had a bid for Morrison rejected by West Ham.
Meulensteen coached Morrison through Manchester United's youth systems during his time at Old Trafford. West Ham's hackles have been raised because Meulensteen claimed that the player 'wanted' to join Fulham.
"Yes, we did make a bid," Meulensteen said after the 3-0 win over Norwich. "Yes, I think he does want to come.
"He would add pace, power, unpredictability and a real attacking threat. I don't know what the situation is now, because that's left with our director Alistair Macintosh."
United academy product Morrison, who left Manchester in 2012, has impressed at Upton Park this season after a loan spell with Birmingham last term.
If the Premier League deems Fulham are in breach of the rules the club could face a reprimand or fine - it is also possible the case could be referred to the Football Association.
