Tammy Abraham (2) and Mason Mount were the goalscorers for the Blues in what was a very end-to-end game.
One concern for Lampard was the manner in which Chelsea conceded both of Norwich's goals, and another will be a potential injury to Mount.
The 20-year-old was taken off in the 91st minute after receiving a kick to the calf. He was also stamped on by Ben Godfrey 10 minutes earlier.
It was a nasty piece of play from Norwich's defender, who tried retrieving the ball but stood straight on Mount's right foot.
Chelsea fans are convinced it was intentional and that Godfrey should have received a red card from referee Martin Atkinson.
But he wasn't and what's worse is that VAR reviewed the incident and decided no further action would be taken.
Check out Godfrey's stamp on Mount below.
How was nothing done about that?
Godfrey played it as if the stamp was accidental, but he appeared to move his foot away from the ball and more towards Mount's foot in the slow-motion footage.
