Chelsea boss Antonio Conte admits Tiemoue Bakayoko still has much to improve.
He played in the 2-1 win over Leicester yesterday and his defensive work impressed Conte.
But he also said: "I think Baka is improving his physical condition and also starting to understand and adapt himself our style of football.
“For sure he has to improve with the ball, without the ball he is very strong, in this game he helped us a lot and after the Leicester goal.
"He is a young player and a good signing for us. He has a lot of space to improve. Like N'Golo, he has to improve with the ball."
