QPR loanee Tom Carroll wants to "make it at Tottenham" but is prepared to consider all of his options at the end of the season.
Ilkay Gundogan has commited his future to Borussia Dortmund by signing a new contract.
Birmingham boss Lee Clark has admitted that they could be forced to sell goalkeeper Jack Butland during the January transfer window.
The cash-strapped Championship club are willing to listen to offers for any of their players due to their on-going financial concerns.
Clark insists that they have not received any bids for England Under-21 international Butland this month, despite several enquiries amid speculation linking him with a host of Premier League sides.
Southampton saw their approach, understood to be in the region of £6million, rejected in the summer, while Newcastle and Liverpool are among a number of top-flight clubs reported to be monitoring his progress.
Clark said: "The only official bid the club have had is the one that was turned down in the summer from Southampton, just as I was taking the job.
"That's not to say we haven't had lots of interest in Jack and people asking the question.
"But, in terms of somebody actually putting down that they want to take him and what they're willing to pay, that hasn't materialised.
"With my football manager's head on, I don't want that to happen. But, in terms of the future of the club, it's been talked about already by the chairman that it probably needs to happen."
