Mount is on-loan at Derby this season from Chelsea.
Lampard assessed: “This is a fantastic opportunity for him to really show the world, and England, what he can do in the Championship.
“I'm aware that they're (England) aware of him. I know he trained pre-World Cup with the squad.
“I know Steve Holland pretty well. I speak to Steve and I know he's on the radar, and so now it's up to him.
“This is why this is such a good platform for him because we are always crying out in England for talented midfielders that can link play, are intelligent and score goals. I think Mason can have a big future.
“He can offer Derby a lot — and I think we can offer Mason a lot as well."
