Galatasaray in terms of performance and team can be seen to be better than Ajax. but they cannot underestimate Ajax. they will play at home and of course, will give everything to win. Galatasaray did play well but sometimes their game was quite chaotic or they had difficulty maintaining a goal advantage.
Although Galatasaray is quite strong in this season, surely they must be careful to play against any team in Europa league. Moreover, it is against Ajax Amsterdam which is one of the big teams in Eredivisie league. The match will be held in Ajax home as well. I also think it won't be an easy match for Galatasaray. However, I believe Galatasaray can get points against Ajax if their defense can play solidly. IMO, the weakest part of this team is in the defense line, the coach must apply a proper strategy that can strengthen their defense. Just don't play very offensive which can lead the defense to be difficult to cover all the areas.
