Chelsea forward Christopher Nkunku has revealed he is still not 100 per cent fit despite a positive start to pre-season.

The France international has scored in each of Chelsea’s first three pre-season matches and has earned praise from his manager. But when asked about his fitness, Nkunku appeared cautious about making any statements that his issues were now behind him.

He said: “I know I am not 100 per cent now, but I am working towards it and I hope soon I will be fit.

“I am feeling better since last year. I just want to do a good pre-season and be ready for the league.

“Top scorer [in pre-season] is just a detail. I just want to be fit and find my level.”

Nkunku, who has predominantly played in midfield but also on the wing, adds he is happy to stay a versatile option for new manager Enzo Maresca: “For the moment, I don’t have a favoured position. We are still in pre-season.

“We just want to work and accept the idea of the coach.”
