Manchester City boss Pep Guardiola says the club will treat Vincent Kompany's latest injury with care.
Kompany, 30, suffered a head injury in a collision with his own goalkeeper Claudio Bravo in the 2-1 win at Crystal Palace on Saturday and will be assessed ahead of the Champions League clash against Borussia Monchengladbach on Wednesday.
"He had a problem with his head," Guardiola said. "[He got] a kick. Now we're going to control him. You have to be careful with head injuries. Hopefully it won't be anything serious.''
The win left City in second place in the Premier League, below leaders Liverpool on goals scored, and Guardiola felt it had been hard-earned.
"It was really tough. Obviously it was not our best performance,'' he said. "We were not brilliant, but I'm so proud of my players in the same way I was so proud against Everton and Middlesbrough, when we deserved to win and didn't.
"It was so uncomfortable because Palace are such a tough team and did so well, and we were lucky to win the game in the end and be up again [near the top]. We will analyse what we can do better, because there are a lot of things we can do better. Now we focus on qualifying in the Champions League.''
Guardiola may recall John Stones and Ilkay Gundogan for the Monchengladbach match after both were rested for the game against Palace.
