Galatasaray after beating Manchester United in the UEFA Champions League competition at Manchester United's home ground last two weeks grew in belief that they're are strong and capable enough to defeat any team in the competition and that's why Bayern Munich should be very wary of the the Turkish club when they face each other next week.
Bayern Munich for a fact has a better squad than Galatasaray in terms of quality of players but considering the fact that Galatasaray are yet to be defeated both in the Turkish Super Lig as well as the UEFA Champions League, beating them at their home will be a very difficult task.
I don't think Galatasaray can beat Bayern Munich in the Champions League because Bayern is stronger and has more talented players than them. If Manchester United does not improve their qualifying performance, I believe they will not advance to the round of 16 of the Champions League competition because even Copenhagen has a point in the group stage, but I am confident Manchester United will do everything in their power to beat Copenhagen next week, Because if they fail to overcome them, Manchester United will not qualify for the next stage of the competition, Bayern Munich has already qualified it will be Manchester United or Galatasaray will qualify with them but Galatasaray has a better chance than Manchester United in the group to qualify.
So basically it is quite difficult for Arsenal to get the full three points against Sevilla. I'm pretty sure that this match has a tense intensity. Sevilla can overwhelm Arsenal even with ideal players. Personally, I would not underestimate Sevilla if they were playing at home. This is a tough task for and his troops to better control their emotions and be calm. As usual, the mentality of Arsenal players will always be tested and in the Champions League competition it will not be the same as what they experienced in the Premier League.
Arsenal is performing well, and I believe they will defeat Sevilla because Sevilla is not in good form more than Arsenal this season. If you compare their league positions, Arsenal is in second place in the Premier League table, and they are fighting for first place, and Sevilla is not in good form this season. However, because Sevilla is playing at home, they will have an advantage to win or draw but it will be difficult for them to defeat Arsenal, because if arsenal make any mistakes they will top the group and he will be a difficult issue for them because Len is already topping the group and am very sure Len will defeat PSV and again is and opportunity for arsenal to perform well and win their match against Sevilla but I truest Arteta he will do his best to win the match.
