Agbonlahor endured a barren spell at the end of last season and the start of the new campaign, but he has recently clicked into form and netted four times since January.
He has always carried an attacking threat due to his pace and Villa boss Lambert has been pleased with his performances of late.
Lambert has other options at his disposal for the run-in and is confident his team can pull clear of the relegation zone in their remaining seven games.
Speaking about Agbonlahor, Lambert enthused: "I think he has been excellent.
"I think he's loving his football at the minute, is scoring quite regularly at the moment and when Gabby gets a run at you, there are not many people going to catch him.
"He is playing extremely well at the minute and if we can keep him, Charles N'Zogbia, Christian Benteke and Andreas Weimann fit we've got loads of options up front.
"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. He has added goals and that's why he is enjoying it. He looks sharp in training."
