Benjamin Mendy is heading to Barcelona for further tests on a knee injury amid fears it could be worse than first anticipated.
The Manchester City defender, who joined from Monaco for £52million in July, was forced off during the 5-0 thrashing of Crystal Palace on Saturday.
Mendy’s knee was heavily swollen after a challenge by Andros Townsend and a first scan proved inconclusive.
City medical staff hoped the problem was an impact injury but more tests should determine whether there is any ligament damage.
The France international will be seen by knee specialist Ramon Cugat, who recently aided Ilkay Gungodan’s long-term recovery.
City sources stress they will not know the full extent of the damage until the end of this week.
