David Sullivan says West Ham are still hoping to sign Alex Song from Barcelona despite the arrival of another midfielder.
“I can assure you we have not given up on Alex Song yet,” said the club's joint-chairman.
“Before Christmas Alex was outstanding and if we believe we can get him back to that sort of form and maybe with a new manager we can, we would very much like Alex to come.
“We are very thin on the ground with midfielders. You do get injuries and you need back-up. We have got Europe and other games that we want to win.
“There was not enough competition for places last season and this year we don't want the same again.
"If the players have a bad game they will have to fight for their position.”
Song played a key role in getting the Hammers to fourth place in the Premier League before Christmas last year but his season-long loan in east London has now lapsed.
Sullivan's comments came after the club announced it had secured the services of another midfielder, Pedro Obiang from Sampdoria.
It is thought West Ham would have to spend £5million to acquire Song from Barca.
