Fatih Terim was in a downbeat mood after defeat to Real Madrid and apologised to Galatasaray’s fans.
The Turks were hit with a 6-1 defeat at home to Carlo Ancelotti’s side, despite a bright start, to begin their Champions League group phase on the back foot.
“There's not much to say after a defeat like that, but we lost the game in a terrible way,” Terim told reporters after the game.
“Madrid didn't have a chance in the first half, whereas we had three or four. We suddenly conceded goals without any apparent reason.
“We started the second half well, but following a dreadful mistake the score became 2-0.
“After that my players gave up the game, because both physically and in terms of morale you can't fight against the situation.
“The result could have been worse, it's such a shame. Sometimes it only takes little mistakes against an established team who are slightly better than you.
“At this level, there is no room for sympathy. I apologise to the Galatasaray fans, all blame is on me. The first goal we conceded was the turning point in the match.”
