A club that's yet to record defeat in the Turkish Super Lig after seven matches can't be an easy opponent for Manchester United that has lost four out of the seven league games they've played in the English Premier League this season.
So many people are of the opinion that Manchester United are gonna beat Galatasaray since the game will be played in their home ground Old Trafford but they don't play at their best, I wouldn't be surprised to see Galatasaray pick up all three points from that game.
As the match against Galatasaray will be held at Manchester United's home ground, everyone is favoring Manchester United in this match but if the last league performance of both teams is considered then Galatasaray will be much ahead of Manchester United.
You may say that English Premier League and Turkish League are not two equal leagues, but consistency is important even though two leagues are not equal.
Since Galatasaray is consistent in the Turkish league, they will get enough confidence against Manchester United and they can plan to win, on the other hand, since Manchester United is not in a good position, they will be a little behind in terms of confidence in this match.
I think the fans will be more happy if Manchester United wins this Champions League match, so I hope Manchester United give a good match at their home ground.
