The UEFA Champions League competition is a competitive competition, and Turkish teams are not strong enough to compete in the UEFA Champions League competition. That is why they find it difficult to get good results in the UEFA Champions League competition.
UCL is the highest level of football club competitions, there is no doubt about how competitive it is. Only the biggest teams in European leagues which can join UCL, so average teams have no chance to join. However, we can't underestimate Turkish teams because they are quite strong teams as well. If you take a look their squads, you must be aware of many star players there.
But let's see if Galatasaray will try to get good results in next season's UEFA Champions League competition since they have signed Victor Osimhen from Napoli this season.
Galatasaray and Fenerbahce are the strongest teams in Turkish league. They have improved their squad very well. Galatasaray have Osimhen, Leroy Sané, and Mauro Icardi. Meanwhile Fenerbahce has Jhon Durán, Talisca, and Amrabat. These are talented and experienced players. So, we should be optimistic about their performance in UCL this season.
