Aston Villa boss Martin O'Neill can't see Manchester United's injury problems being a problem for them ahead of this weekend's clash.

O'Neill anticipates a tough test despite United's injury list which led them to parading Michael Carrick, Darren Fletcher and Park Ji-Sung in their back four against Wolfsburg in the Champions League in midweek.

He said: "If you had listened to Sir Alex Ferguson talking before their European game, he mentioned that the most important thing for him was Saturday's game against Aston Villa.

"He might not have every single option available to him but he'll have a lot more options available to him on Saturday, you can guarantee that.

"Manchester United couldn't have won the number of championships they have without having one of the strongest squads in European football."
