Galatasaray also confirmed that Victor Osimhen suffered a fracture to his right forearm during the first half.
The Nigeria forward went down holding his arm following a challenge with Ibrahima Konate in the eighth minute, but he played on until he was replaced by Leroy Sane at half-time.
“Following the match, a check-up at the hospital under the supervision of our medical team revealed that our player had a fracture in his right forearm, and a cast was applied,” Galatasaray said.
“A decision regarding surgery will be made in the coming days after further evaluation.”
Buruk complained about referee Pawel Raczkowski’s decision-making following Osimhen’s injury.
“Looking at Osimhen’s position, we saw that Konate was able to commit these fouls very easily, he could easily apply any kind of foul,” Buruk said.
“While we were expecting the best referee in the world, perhaps one of the worst referees officiated the game.”
