I don't think you are thinking this through. Yes He's at the best club, but Mourinho is always looking to challenge himself and expand upon and improve his Resume. As much as we don't like to hear it, he doesn't really have an overwhelming Loyalty to one club (Maybe Slightly towards us, seeing as how this is where he became super famous) which is why he's moved from club to club, even after winning the UCL with Inter. IF, Mourinho wins the UCL along with the La Liga (which is in the bag now) than I can see him moving. If not this year than the year after. He will want to move back to England IMO. Which club? Who knows, Hopefully us. You may say, 'why on earth would he choose us, if he's trying to add to his resume why would he come back to Chelsea, wouldn't that just be been there done that for Mourinho?'. Well yes and no, but one thing he never won with Chelsea is the UCL. Plus he never wanted to leave. A mixture of factors forced him to leave. Otherwise who knows how long he could have stayed...
