Despite his impressive start, Dembele insists he is not a replacement for the Croat.
He said: "Before I came to Tottenham I was a big fan of Modric. For me he was one of the best in England, but I am a totally different player.
"He had different qualities and I don't feel I have to do exactly what he did.
"I play my own game. I try my best to be as important as he was and that would be a great achievement. But I'm not him."
