Mourinho hasn't had much luck in recent years. He's been at so many clubs he hasn't managed to achieve anything. It seems like his magic has run out, or maybe he's not going to the right place. The signings he's made at each club he's been at in the last five years are very questionable. While Galatasaray signs good players, Fenerbahce signs ineffective ones. It was difficult to compete that way. When he was Manchester United's coach, he made some strange signings. Roma also made some strange signings, but they had many good players on loan, such as Lukaku.
Tottenham also made strange signings. The fact is that for some reason I don't understand, it seems he doesn't like having top players in the spotlight, which is a mistake just like the current Manchester United coach is making. Top players like victor osimhen bring big and positive changes to the squad they're in. Fenerbahce was only behind strange, dull players. How did they expect to achieve something like that? it was impossible
Fenerbahce wanted to get the Champions League and they hoped that Mourinho could give it to them, but when it didn’t work out, they decided that changing the coach was a better solution. By the way, Solskjaer was also fired, so both coaches were fired from the Turkish League almost at the same time. I didn’t follow Besiktas, but I see that they were left without the Conference League because they couldn’t beat Lausanne. But Solskjaer was never a coach with great achievements, unlike Mourinho, so maybe he shouldn’t have been fired.
