Sunderland manager Martin O'Neill insists he will not buy any players for the sake of it this winter.
The Northern Irishman has got the Black Cats back on track with four wins and a draw since taking over from Steve Bruce in early December but is in no hurry to add to his squad during the January transfer window.
"It's the injuries that would cause you more concern - you can deal with suspensions, they are part and parcel of it, but that definitely causes you a concern.
"The truth is this here, that perhaps if we are wanting to try to compete, first of all you would like to be as healthy as possible and you would like to be as strong as possible.
"If you get a spate of injuries in the first or second week of February, then you can't do anything about it, so from that viewpoint, it becomes a bit manic.
"Football clubs have tended to stay off it until the last possible moment and then suddenly in the last few days, there's a lot of movement.
"But most managers would be thinking along the same lines: what they are concerned about is not having the requisite number of players at your football club for the very, very important next few months.""That's something I will monitor," he said.
