Nkunku set to become Chelsea's key man

Christopher Nkunku has played 398 minutes, more than any other player during Chelsea's pre-season tour and looks set to have a starring role this season - if he can stay fit.

Like last summer, the Frenchman again excelled in pre-season and netted three goals in five matches on tour, playing in several different positions, including as a striker and central midfielder.

Last summer, Nkunku suffered a knee injury in the final match, which began a chain of different injuries to limit him to just two starts last season.

Nkunku said he wants to stay fit first and see where his football takes him, admitting that he is still "not 100%".

But Enzo Maresca clearly likes the versatile star and said: “Christopher was injured for almost all of last season but I knew from Germany how good he is. He has surprised me but it is not a big [surprise]."
