Sunderland boss David Moyes has admitted he is unlikely to be able to bring in any players this month who could make a "big difference".
The Black Cats are understood to have tabled a bid for Norwich's Robbie Brady, reportedly in the region of £10million, although Moyes is not expecting any arrivals of that magnitude.
He said: "I'd be kidding you on if I said the players we are going to bring in in January are going to massively make a big difference because first of all, we probably couldn't get that level of player and secondly, we probably wouldn't have the finances to do that.
