Think at this point Mourinho should just take a break for a year or two like Klopp did, take a job with a team like PSG/Juventus/ACMilan when they become available bring the usual trophies home + the CL and retire on a high
I can see him being like Wenger and ferguason though managing into their 70s, if I had their money I would have retired by 50-55 and spend the years after that enjoying it
