Aston Villa boss Paul Lambert has hailed his current number two keeper Shay Given as world class after helping his side stay on course for a potential cup double.

Lambert believes Given is unfortunate not to be playing on a regular basis because of the form of Brad Guzan despite Villa leaking 17 goals in their last four Barclays Premier League games.

Given again showed his ability with two superb saves during yesterday's 2-1 FA Cup third round home win over Ipswich ahead of Tuesday's Capital One Cup semi-final first leg at Bradford.

Lambert said: "I think Shay has been unfortunate because of the way Brad has been playing as well.

"Shay Given is a world-class goalkeeper but Brad Guzan has been playing fantastic for us as well.

"Shay makes saves that I think are impossible to make. He is very good.

"If you ask the young players in front of him, they will tell you what they think of him as well.

"I can't speak highly enough of the way Shay plays. I thought the save he made in the second half was world class."
