Manchester United defender Jonny Evans says they must not take Wigan Athletic lightly.

United face the Latics on Boxing Day.

He told manutd.com: "A few years ago [January 2009], we only beat Wigan 1-0 when we were going on a long run of clean sheets. It was a very tight game at Old Trafford.

"I know at the minute they're near the bottom of the league but they've had some decent results in the last few weeks and I think it will be tough.

"When I used to watch as a fan I remember always thinking the away team never really tried to score. They'd just sit back and play one up front.

"But I think there's been a bit of a shift in that philosophy in the last few years. Teams are coming here and thinking they may as well go for it. I think sometimes it's easier said than done. It's different when you get out onto that pitch - it's a big pitch and we're so dominant at home.

"I still don't understand why going away from home has such a big effect on performances. But it does and, on the flip side, we're particularly good at home. Our home form last year at Old Trafford won us the league."
