Aston Villa boss Paul Lambert is confident they have the quality to cover the injury of Ron Vlaar.

Jores Okore and Ciaran Clark formed a partnership in Vlaar's absence this season when he had a calf injury and Lambert has no issues throwing them back together.

"The two of them have been outstanding. To be fair to the lads we have the fifth best defensive record in the league and they have been a major part of that," he said, ahead of Saturday's Barclays Premier League trip to Leicester.

"The back four and Guz (Brad Guzan) shows you the cornerstone is pretty strong."
