Aston Villa boss Martin O'Neill is wary going into their clash with Wigan Athletic.
Villa are favourites after Wigan's thrashing at the hands of Bolton Wanderers on Saturday.
But O'Neill is not so sure: "They've had a strange season. At times they have played brilliantly in matches and then they've had some other indifferent performances.
"They shipped in nine goals at Tottenham but their win over Liverpool just over a week ago, a game I was at, was fantastic.
"It has been topsy turvy for them this year but the fact they defeated us, Chelsea and Liverpool shows it is a game to be taken very seriously."
