Owen Coyle has one of the smallest squads in the Premier League, but has managed to launch his team into the top six despite failing to fill the bench against Chelsea recently.
He is stretched, and with the club in debt to owner Eddie Davies to the tune of £90million (even though he is not planning to call that in soon), Coyle may have to trade his way through January if he wants to make any additions.
David Jones of Wolves could be prised away from Molineux with the promise of Premier League football for seasons to come. Midfielder Ivan Rakitic, who is desperate to leave Schalke 04, is another who interests the Scot.
I think he will allow Cahill to leave if they can get anything near his £17million buy-out clause, and do his best to keep Elmander.
POSSIBLE INS: David Jones, Ivan Rakitic (Schalke)
POSSIBLE OUTS: Gary Cahill, Johan Elmander
