A simple comparison between Aziz Yıldırım and Ali Koç presidency eras at Fenerbahçe. Only 1 Turkish Cup trophy in 7 years is just terrible. But he still doesn't want to step down from his position.

Galatasaray isn't doing this for example. They have seen many different presidents in years. But this isn't a very common thing to be seen at Fenerbahçe. This is the main problem of not being able to win the Super League for years.
Osimhen clearly made the biggest difference for the whole season. Without Osimhen, Fenerbahce would have won the league, but Osimhen came in, out of nowhere, and made Galatasaray the champions .There were long stretches where he literally carried the team all by himself. I am not saying other players were bad, they were good or decent too, but Osimhen is on a whole another level.
Fenerbahce should keep Mourinho though, paying him a big amount to fire him is not smart, keep him, get some good players, and rebuild, and he will try to do again. I think he has one more year and that's it, so instead of firing him, keep him and pay him to run it one more time, I am sure they will do at least this much good, if not at least decent. That is the most important part for them, consistency.
I agree about Osimhen. He is a complete game changer and Galatasaray wouldn't have been able to become champions without him. Mourinho is also currently being criticized a lot because of his derby results and comments contradicting the reality.
