"The one thing that was lacking in his game was goals. His stats from that point of view up to the West Brom game weren't great but what he does bring is genuine pace to the game and a threat.

Aston Villa slipped to 18th in the table following a 2-1 home defeat to Liverpool on Sunday but Lambert is confident that Agbonlahor and his other attacking players have what it takes to drag the team away from the relegation zone.
"If we can keep him, Charles N'Zogbia, Christian Benteke and Andreas Weimann fit we've got loads of options up front," he enthused.
