I saw your messages getting after people who said differently to you. That's what I was bothered about.Did you see the amount of messages immediately after the defeat? All saying how Pep can't deal with this situation, or how this is his last sesson, or how he lost the game because of no subs.
Of course a doctor has a huge saying in how long a player coming back from injury can play. From previous press conferences Doku was not expected to play until after the international break. Even more if you focus on his minutes, you see he didn't have his explosiveness and acceleration. He was being very careful.
And a doctor is not going to say "10 mins". It an absolute nonsense. A doctor is going to detail potential risk. Not, 10 mins fine, 20 mins bad, 30 mins dead
