Aston Villa boss Paul Lambert says they go to Manchester United confident of an upset.

Lambert's side were unfortunate to lose 3-2 to United in the reverse fixture at Villa Park earlier this season, having led 2-0 only for substitute Javier Hernandez to score twice after Ron Vlaar's own goal.

The Scot believes Villa can take heart from that performance. "They're used to playing that kind of football every time," he said. "They can bring on the likes of Javier Hernandez.

"We gave them a right good go that night, but they're used to doing that to teams. We were disappointed to lose but it was no disgrace."
