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.
