Aston Villa boss David O'Leary admitted a "mad five minutes" cost them after a 3-1 defeat at Manchester United.
He said: "It was a mad five minutes when we gave two silly goals away and they punish you for things like that.
"We had chances in the first half but gave another silly goal away. We were thinking positively and got back into the game but didn't pass it after that.
"If Juan Pablo Angel does start scoring goals it will be a great help for us because he hasn't been for a while."
