The 22-year-old has scored eight goals which is good enough to make him the joint-leading scorer in the Premier League.
Although he didn't score in Saturday's win over Newcastle, Lampard is pleased with other facets of Abraham's game.
Lampard said: "He has been scoring goals regularly but today was not quite the norm. What you do see with Tammy is what you get - physicality and movement. To keep trying and be a problem for the defenders. I have got nice problems up front.
"We have got Giroud and Batshuayi. I have to give them both credit because they are showing great professionalism. They are training at a level. They will get their chances as well because it is a long season.
"At the moment, Tammy, with his regular goals, has been a big part of getting us to where we have got to at the minute. He has been playing. I think he can [get even better].
"He is a sponge. He wants to listen. He wants to get better. He wants to improve his game. He wants to score more goals. He wants to help his team-mates. And so he has got a beautiful base of that in terms of coaching. So I think he has that.
"His goals and performances will show what he can do at this level. Hopefully, we can move him up the levels even more."
