Lambert has told Chelsea that Crouch is not for sale - but a deal for the striker could yet materialise.
"I've no intention of letting him go," Lambert said after seeing his new charges beat Huddersfield 2-0.
"Peter has a great work ethic, knows the game really well and is an absolutely fantastic professional, the way he conducts himself.
"His game hasn't changed since he was a young guy. He's never going to run in behind - that's not his game. But what he has got is an incredible presence and a lovely touch for a big guy. If there's a nicer person in football, I've yet to meet him."
