Manchester united playing Galatasaray at Galatasaray's home in their next champions league fixture is definitely going to be another though one for Manchester united as that fixture is a determinant for Galatasaray and they will be playing form home against Manchester united.
Galatasaray would not want to give a chance to Manchester united on this one because if they loose they are definitely going to be affected with their chances to qualify, they have four points with Copenhagen which is at the second position on the table, if they win and Copenhagen loose to Bayern Munich they are definitely sure of qualifying but if they draw then Copenhagen will have to loose for them to be sure of qualifying so the best alternative for them is to win which they are definitely going to make to that in their home, currently it looks like Manchester united with their current form needs a miracle to qualify.
The competition in Group A does look interesting, especially considering Manchester United uncertain performance, even though we certainly know that the clubs in the EPL have strength in terms of players, but unfortunately Manchester United is currently experiencing a significant decline and it even seems impossible for Manchester United to qualify for the round the last 16 because the remaining 2 match that Manchester United will face are quite difficult, namely against Galatasaray and also Bayern Munich.
Regarding the next match, I thinks Galatasaray will be more favored as the home team and what is certain is that Galatasaray will not waste this opportunity and fight hard to be in second place so they can qualify for the last 16.
While Copenhagen seems difficult to beat host Bayern Munich their draw is also not certain because Bayern Munich did not give any club the opportunity to steal point from them.
