"I don't think it's a new level for Ross," the boss determined. "I played against and with Ross, for England, and he's got great quality. What he's doing now is playing a very complete role, with his work-rate, recovering and jumping out to defenders from midfield areas, and he always has that goal threat with his technical qualities of right and left foot.
"Ross has been dedicated to the cause in lockdown, in his performances just before lockdown, and I'm delighted with him. He just needs to keep his levels. I'm delighted with him and his attitude has been first class.
"I can't pick all of my six or seven midfield players," added Lampard.
"Certain games dictate whether you want to be more offensive or not. When Ross and Mason were really positive on Saturday it was great, it changed our game, to get the ball through the lines and in to Christian and Willian, and to get themselves into high areas. That is key in those sort of games."
