David O'Leary has challenged Aston Villa striker Luke Moore to become more clinical in front of goal.

Moore scored five goals in three matches, including a hat-trick against Middlesbrough, before drawing a blank in Sunday's FA Cup tie against Manchester City.

O'Leary has been delighted with the progress of the England Under-21 frontman but believes he must convert a higher ratio of chances.

The Villa boss said: "Luke has potential but he still has a long way to go. When he gets chances he has to put them away as he did at Middlesbrough.

"He has to score more goals. He will not be judged over a few games but on whether he can produce repeatedly."
