Wigan Athletic boss Steve Bruce admits he must shop abroad this January.
He said: "If I can bring in two or three players that would be good but I will only bring in new players who can improve us. The January window can be difficult because it's very hard trying to prise players away from clubs, especially those still playing in Europe.
"The English clubs are still in Europe so they'll want to hang on to their players and this tends to have a ripple effect throughout the League.
"I have to strengthen but saying that every player has been fantastic since I came in."
