Sunderland boss Martin O'Neill is anxious about having a successful winter market.
O'Neill is desperate to strengthen during January.
"Once February 1 comes around, it's a long time after that until the end of the season where you're not able to change anything.
"In fairness, I think most clubs will be trying to do something. The exceptions are the main sides who have the wherewithal to cope with anything, but numerically, we're not that strong.
"We have less players than most people in the league, so we really have to look to do something if we can. I accept it's not going to be easy, but some of the fine players we have at the football club probably need a bit of help."
