Gabriel Jesus admitted the fear of serious injury is preying on his mind after a number of serious setbacks.
The Manchester City striker made his first start in over two months in defeat by Basle following a knee injury which left him in tears at Crystal Palace on New Year's Eve.
Jesus had come off the bench in City's previous three matches but conceded he is not yet in the right frame of mind.
'When you are in the game you end up thinking about the previous game when you got injured,' he said.
