The midfielder was replaced by Marcus Rashford after leaving the pitch clutching his hamstring in the Europa League on Wednesday
Manchester United face a nervous wait after Henrikh Mkhitaryan picked up an injury during his side's Europa League clash against Saint-Etienne on Wednesday.
The midfielder opened the scoring at Stade Geoffroy-Guichard to put the Red Devils 4-0 up on aggregate and maintain his fine run of form of late.
However, Mkhitaryan was soon replaced by Marcus Rashford after leaving the field clutching his hamstring, leaving United sweating on his fitness just days before Sunday's EFL Cup final against Southampton.
