Lambert said that he was impressed with how quickly Bennett got back up to speed after months out with injury, and agreed that he would be in contention for a start at the weekend against Stoke City.
"He's had a hard time but that performance was excellent," Lambert told the Birmingham Mail. "I never really waver when a lad goes on to the pitch.
"If they are out there I believe they'll go and do the job and try their utmost, so I trust them to go and do their best. He was outstanding. It was his first game there for months and months and I thought he was absolutely terrific for us.
"He made a brilliant tackle in the first half when the ball got whipped across the six-yard line and he cleared it. He was up against a guy that cost millions and it was a mammoth performance from Joe."
Villa are currently 10th in the Premier League, nine points clear of relegation danger.
