Sam Allardyce could not confirm whether or not Jermain Defoe will still be at Sunderland in January.
As the Black Cats strive to get their flailing season back on track, Allardyce spoke of the uncertain transfer plans of the Wearside club.
Quizzed on the future of Defoe, who has scored four goals in the Premier League this term, Allardyce was non-committal either way regarding the 33-year-old former Tottenham star.
"At the end of the day, whatever happens, happens," he said.
"If I ring an opposition manager or football club and I want one of their players, what determines if that player is available or isn't available changes day by day. There's no definite players that we know of going out from here. In terms of a specific player, we don't know.
"At this moment in time, we don't know a definite player who is coming in, because we're just starting to pull up who we think might be available."
On the overall transfer plans of Sunderland, an undecided Allardyce added: "I think the business done in January will be minimal.
"I don't think it will be extensive. It's too small a window to find what you need, which are players of greater quality."
