Benteke continues to justify Lambert's decision to prefer the Belgian international to fit again record signing Darren Bent after netting the only goal at Villa Park. The £7 million summer signing from Genk has quickly become a fans' favourite at Villa Park while Bent cannot even command a place amongst the substitutes.
Lambert said: "Christian has been excellent. You run out of things to say about the big guy. He has turned himself into a fans' favourite here, that's for sure, and his general game is outstanding at the minute. He has been brilliant for us. I thought the header for the winner against Reading was fantastic."
The Scot added: "You forget he is only 21 and he might not hit his peak until his late 20s but he is playing ever so well for us."
Benteke is used as the only out and out striker in a 4-2-3-1 formation and Lambert said: "You've got to be a special type of player to play that lone striker role. He has also been fantastic for Belgium and he is getting better with every game.
"He is developing his whole demeanour...he is growing up. he is a strong lad but also has really good ability. He does get on the end of chances. I've been delighted with him."
Leaving Bent completely out of his matchday 18 for the last two games has been a big call, after the striker recovered three weeks ago from an ankle setback, given his goalscoring record. It has led to speculation that the former Tottenham and Sunderland player, who was given and then had the captaincy removed by Lambert, will leave Villa in January.
But Lambert insisted: "I do pick a team honestly as I can. You can't please everyone all the time. You leave out people like Ireland and N'Zogbia, Given - big players. It is never to pick a team because you have that many lads to look after but I've got 25-26 lads I have to look after.
"I've not had one problem with any of the lads. The most important thing is this club and I'll always make decisions I think are right for this club."
