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.
Yes, you are right, Galatasaray should not underestimate Ajax just because their current position is better in the European league standings. Because if we look at Ajax's performance in the Eredivisie, it can be said that its performance is quite good. Therefore, I also agree, that Galatasaray really has to play at full strength, so that the results that can be obtained from this match are truly satisfying. Moreover, the match against Ajax is the last match in this preliminary round. So Galatasaray really has to fix the weaknesses it has from now on.
Apart from that, if we look at the head to head record between Ajax and Galatasaray, the result is that Galatasaray is superior. But this certainly cannot be a guarantee that Galatasaray can beat Ajax easily. But even so, it is very likely that Galatasaray has great potential to win this match. So the most important thing is that Galatasaray's players must maintain their physical fitness, so that no one suffers injury. Because if Galatasaray's important players are injured when facing Ajax, I think this will be a bad thing.
