Chelsea manager, Mauricio Pochettino, has confirmed that Christopher Nkunku will miss three to four weeks after picking up yet another injury.
Nkunku is undergoing a medical assessment with the Premier League club.
Pochettino, speaking to the media ahead of their FA Cup clash against Leeds, admitted that the 26-year-old is no longer the player he used to be at RB Leipzig.
He said: “We learned yesterday Nkunku got injured but we don’t know when he got injured.
“We need to see and evaluate every day but he’s out for three or four weeks. We hope no more.
“It’s difficult for him. We watched him when he arrived in pre-season.
“He was flying on the training pitch until he got injured. Now it is nearly eight months and he has been involved again but he is not the same player as before.”
