There is no one (especially a coach) who does not like money in any case if an offer comes to him, but if the amount is not too large than the offer made by a great club. Of course Mourinho would choose to coach a great club rather than have a career in a certain league with a club that is not great, but if the offer could be quite tempting for him. I think he will also go to Saudi Arabia if someone wants to use his services as a coach who is experienced and also great at football.
I have seen that there are many rumors related to Jose Mourinho with big clubs from the Premier League, be it Manchester United or Newcastle United, where these two teams are reportedly interested in using Jose Mourinho services. Apart from that, after Mourinho was fired by Roma, of course a bigger opportunity might come from the Saudi Arabian league team because Mourinho was linked with a Saudi Arabian team in the previous transfer window but he refused and for now the Saudi Arabian league team certainly has one chance once again to tempt jose mourinho to become their coach.
I think Mourinho can get a fairly large salary if he joins a Saudi Arabian league team because currently teams from the Saudi Arabian league offer salaries large enough for attract top European coaches to join them. Everything will depend on Jose Mourinho decision, where if he wants to leave the European stage, of course the Saudi Arabian League will be his destination. But if he wants to coach a European club, of course the Premier League will be his next goal. This season there have been two Serie A teams who fired their coaches, especially Napoli who fired Rudi Garcia and Roma who fired Jose Mourinho. Even, Pioli will also suffer the same fate. If he is unable to bring AC Milan to become champions this season, he will definitely be fired.
