“We need to make a scan tomorrow, it’s his calf.
“I’m a little bit worried he might be out for several weeks but we need to wait until tomorrow."
Schneiderlin left the pitch with just half an hour played after having aggravated his calf, and chose to leave the pitch of his own accord after receiving some preliminary treatment from the trainers.
With the international break next week, it buys the Blues some time for the Frenchman to heal up, because the first game back is the return leg of the Merseyside Derby against Liverpool in Anfield, followed up by a trip to Manchester United three days later.
Everton’s midfield showed a noticeable drop in performance when Schneiderlin hobbled off with Gareth Barry replacing him. The Toffees have broken into the top six, but will need to pick up some points against the Reds and Red Devils away from home to maintain that.
