Mourinho does not rule out the possibility that he will one day move to Saudi, currently he is still unemployed and without a club. Maybe if one of the SPL clubs is willing to provide budget support to be able to build a squad that suits Mourinho wishes, as well as a large salary, then I think Mourinho will accept it. On the other hand, it is rumored that Mourinho will be approaching to Newcastke, but we cannot use that as a guide, the future of the Portuguese coach is still unclear. It's true, that previously Mourinho was also linked with Napoli, we know that the Napoli President still seems dissatisfied with the performance of their new coach Walter Mazzarri.
The SPL looks like it will spread its wings to recruit top European coaches, they will not only focus on players. Of course they want the image of the club and the Saudi Pro League to continue to improve, by recruiting a coach of Mourinho caliber they can gain instant fame. To be honest, I want Mourinho to just coach the national team, at club level he has experienced various trophies with the clubs he has coached.
This does not rule out the possibility if that European clubs are not interested in appointing him as coach because we know that Jose Mourinho salary is quite large. So even if a mediocre or weak club want to appoint him, they have to think twice about Jose Mourinho salary, and if no European League club appoints him as coach. Maybe he will consider coaching a Saudi League club because it is impossible for him to continue to be unemployed because he has not stated that he will retire from coaching.
Yes, Saudi League clubs don't just focused on players, they also needs coach to improved the quality of their game, especially as Jose Mourinho is a famous and phenomenal coach. If he brought him in, it would be good for the Saudi League itself to increase the league popularity.
Even so, Jose Mourinho still need great consideration even though he was offered a large salary, but if he leaves Europe his fame as a European coach will definitely fade and it could be that his potentials in the Saudi League will not develop well, as is currently the case with many European league players whose potential is fading when in a different league.
