Bayern Munich and Manchester United is the strongest teams on group A so it's hard for Galatasaray to compete against these teams but everything still possible to happend because group stage hasn't to begin yet and if Galatasaray can able to beat Manchester United i think there is a good chances for them to qualified but indeed this is really hard because during their participant in champion league turkish teams always be recognized as mediocre team and the most realistic position for Galatasaray probably 3rd places however if i am not mistaken Galatasaray have been advances to round of 16 on 2013 and at that time they were fight against Schalke and Galatasaray were successfully to advances to quarterfinal but unfortunately their journey have to stopped on that stage because they lose from Real Madrid
In this group, the material players are Bayern Munich and Man United, who seem to have progressed to the next phase. But for Man United, if they fail to enter the top 16 of the UCL, the chance may only be 40%, but the chances of winning the group seem difficult considering the condition of the players present. Moreover, currently players like Sancho and Antony are also experiencing problems and it could be said that the reserve players are also not in good form. So, Man United being runners up in the group is good even though there is a risk of meeting a stronger team later. I think this group will be more exciting than group F, every team has a chance to qualify from that group.
