Mount again impressed for victory at Norwich City.
"It is important he feels like a big player," said Lampard, "because we were a young side today and players like Mason and Tammy [Abraham] for sure, but also Andreas Christensen and Kurt Zouma, players that are a still young, they have to grow up very quickly with personality and be leaders on the pitch.
'When I asked Mason that question he just sort of smiled. He is a confident boy in a really nice way, he has a lot of humility and a work ethic so he smiled and we had a laugh about it but I did not really get a clear answer.
"He should feel like it if he plays like he is at the moment. That does not mean it is the end of the story, he needs to work and get even better daily.
"It is good for our Academy because people have looked at that and asked a lot of questions. I know the work that goes on there with people like Neil Bath who runs it and will be very happy this afternoon and this evening because he has seen two great young lads with a real desire to play for this club. Fans like to see players who really feel the club."
