Steve Bruce has warned Aston Villa they can take nothing for granted when they head for bottom-of-the-table Sunderland tonight.
The former Black Cats boss is currently targeting promotion from the Sky Bet Championship and three points at the Stadium of Light would do third-placed Villa's cause no harm at all.
However, Bruce is wary of the threat posed by Chris Coleman's improving side.
He said: "Sunderland have scored three against Middlesbrough, they've scored three against Bristol City and they've gone to Millwall and got a result at the weekend, so, all of a sudden, they're finding something. They have gone through a tough time, but Sunderland away is never going to be easy."
Sunderland are without a win in seven league games and find themselves four points adrift of safety, although Coleman is not about to throw in the towel.
He told a press conference: "We've got 11 games, 33 points, we're four points from where we need to be after the last game, so that's not insurmountable.
"We are still in there with a big, big chance."
With leaders Wolves not in action until tomorrow evening, second-placed Cardiff will hope to reduce their six-point advantage when they entertain lowly Barnsley, while Fulham will look to maintain their challenge by extending their unbeaten league run to 14 games when Sheffield United visit Craven Cottage.
