Galatasaray was expected to perform better than their performance in the game but despite winning by 3:1 their opponent was not a good opponent that should have scored the team if not for the error from the poor goal keeping by the keeper, Galatasaray remains unbeaten in the league and the issue of scoring goals should be utilized when they play opponents that are weak like Rizespor.
Except you have a very higher expectation I believe Galatasaray performed well in this game, winning by three goals was a good enough victory, a team does not have to win by several numerous goals to be considered to have won well, Galatasaray is still unbeaten and most likely will for the longest. I know it was a weak team they played against but even the week teams do have a way if at least defending their side so as to reduce the number of goals they concedes so we should not be expecting they would have scored too many goals and the opposition would just let them without a defence.
