Cole Palmer is already training outside and on the grass despite breaking his little toe less than a week ago.
While Enzo Maresca admitted he would be surprised if Palmer is able to play Arsenal in this Sunday's showdown with the Premier League leaders, Chelsea's head coach did not entirely rule out the prospect.
The 23-year-old England international is set to miss tomorrow night's Champions League clash with Barcelona in the meantime.
Palmer is wearing a specially-modified boot on his left foot to help aid his recovery after stubbing his toe on a door at home and that is allowing him to train now, with a view to joining the team sessions soon.
