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.
Manchester United is a traditional club in Europe and also gave bigger records in the UEFA Champions League competition than their opponents in their next fixture of the competition Galatasaray but that doesn't mean that they have a better chance if winning that encounter than the Turkish champions.
Galatasaray who defeated Manchester United at Old Trafford in their second game of the season in the competition I think are physically, tactically and mentally better to win that game when the play host the the English Premier League club. Galatasaray will be playing that game knowing fully well that they need nothing but a win if they must reach the knockout stages and that's why they'll definitely give their best in the game to make sure they take all three points from that game
