Manchester United manager Sir Alex Ferguson has been left sweating on Shinji Kagawa's fitness after the Japan midfielder twisted his knee during the first half of Tuesday night's thrilling 3-2 comeback win over Braga.
The result virtually guaranteed the Red Devils a place in the Champions League knockout phase with three games remaining.
But it may come at a price, with Kagawa due for tests on Wednesday to discover the extent of the problem, and Ferguson said: "Kagawa twisted his knee. He struggled on for 20 minutes but we will assess in the morning because we don't know the extent of it at the moment."
