"There is no concern, but we cannot forget what Kylian has done for this team and we miss a bit of support for him. We must not forget that he is our captain and I hope he will be back with us soon," Upamecano told reporters (h/t MARCA).
"There are a lot of games and I said that at the start of the season. We are human beings and the mental aspect counts a lot for us. I'm not going to go into those details, but as I said before he is our captain and I hope he will be with us soon. He is very important for us.
"He's a friend, a super player and I know what he's capable of. I hope he comes back and when he's here I hope he wears the armband."
