Manchester City striker John Guidetti has no idea when he can play again.

On-loan at Feyenoord, Guidetti has been struck down by a mystery virus. He was taken to hospital twice last week after complaining of having no feeling in his right leg. "I cannot exactly tell you what's going on, that's something for the doctors. I am guided by the best doctors and they're doing everything to help me come back. I'm sure it will come good," said Guidetti.
