Real Madrid beat Getafe 1-0 but lost Eduardo Camavinga in the second half to what looked like a knee injury just four days before the trip to the Etihad to face Manchester City.
Ice was placed on Camavinga’s left knee after he appeared to twist it five minutes from the end of Madrid’s dull but comfortable victory over Getafe.
The 20-year-old French international was important for Real Madrid in the first leg attacking from left back and he set up Madrid’s goal.
If he is ruled out of the second leg David Alaba would move to left back and Eder Militao would return to the centre of defence to partner Antonio Rudiger who was one of several key players completely rested for this one.
