Sunderland boss Martin O'Neill is determined to "bolster" his squad before the winter market shuts.

O'Neill was speaking after victory over West Ham United.

He said: "We are trying our best, obviously, to try to bolster the squad, which will be very, very important if we can do.

"But again, the great thing about the win, which is I suppose reminiscent of last year, only for 24 hours or 48 hours it takes a little bit of pressure off. It gives you a bit of respite and gives you a chance to look again."
