It is about the money and it is pretty easy money for him because yes, there is pressure but he knows that with his character everyone else knows if they attack and blame him, he doesn't care and waits for getting sacked, makes money from it and leaves the country again. Mourinho doesn't have this unlimited will to win titles anymore. He is doing the job because it is paid so well, but in the past he has been doing the job because he wanted nothing but to be the best.
I think you are wrong about Jose Mourinho who only thinks about money, he chose Fenerbahce compared to becoming a coach in one of the Saudi Arabian clubs because he did not want to leave the Europa League, even though if Mourinho wanted to leave the Europa League and choose the Saudi League he would definitely get a bigger salary than what he gets now, last season when he was fired while coaching Roma, Saudi Arabian clubs competed for his signature but he waited for a club that wanted to recruit him in the Europa League and it fell on Fenerbahce so money is not the reason Mourinho is in Fenerbahce.
You are right, if we are talking about money then we will see Mourinho in the Saudi Pro League right now, because I think the teams from there are willing to spend more money than Fenerbahce spends, so Mourinho still wants to be in Europe rather than going to a team outside Europe.
This coach's ambition is still very big, so it is quite certain that he also still has a very high desire to present a title to the team he is currently handling. But in my opinion, it doesn't matter that he actually prioritizes money, because his achievements are also very good, so maybe this is the right time for that.
