Shaw, who has provided two assists in 15 appearances for United this season, is in danger of missing the trip to west London after suffering a second concussion injury in as many games against Watford last weekend.

The left-back, who was forced to miss England's two fixtures over the recent international break as a result of the blow to the head he suffered in the 2-0 defeat to City, was forced off inside the final 10 minutes against Watford last weekend, also missing Tuesday's trip to Villarreal in the Champions League.
