I agree with you. A break will make him decide where to go or start from. I believe that he will do better in the Saudi Pro League than in Europe, because his tactics will be new over there. Unlike, in European that his coaching tactics is no longer new to the coaches. Jose Mourinho was an outstanding coaching way back and I cannot forget his wonderful moments and achievements.
A coach like Jose Mourinho should definitely look at leagues other than European ones because he can still improve teams as long as they're not European. I've also quite admired Jose Mourinho in the past when I saw the teams he coached improve, and he was truly renowned for his coaching style when managing one of those teams. But for now, I also think Jose Mourinho should explore other opportunities in leagues outside of Europe so that his coaching prowess can once again be clearly demonstrated at his age.
