United boss David Moyes suggested Villa were lining up to kick the youngster in the game that his side won thanks to two goals from Danny Welbeck and a third from Jordan Henderson.
"My team are not a physical team," said the Scot.
"We are a young side and maybe sometimes over exuberance gets the better of them but I have never sent anyone out to kick them."
The game saw Christian Benteke's barren run stretch to 10 games and Lambert has backed his star man to come good.
"He will come through it," said Lambert.
"His endeavour was there. He is not getting the breaks he had last year but he will go through stages like this in his career."
