Do not be so sure about Manchester United being able to beat Galatasaray. The performance of Manchester United is not consistent at all. It is really hard to trust Manchester United with anything at this moment. So we definitely cannot say that Manchester United is going to win this match against Galatasaray with 100% certainty. if anything, the Manchester United fans should actually be a little scared. Because even never know which match Manchester United is going to perform badly and in which match there are going to be a few own goals.
I'm also not really sure that Manchester United will be able to win when they face Galatasaray at Old Trafford, because up to now Manchester United still hasn't looked consistent in winning matches, including matches that take place at home. So there is a possibility that it will still be difficult for Manchester United to win when facing Galatasaray in the Champions League because in the Turkiye Super Lig, Galatasaray is a pretty good team so there is a possibility that it will make things difficult for Manchester United at Old Trafford tomorrow.
