He didn't do that at Porto; or at Chelsea first time around; or at Inter. I have no idea whether or not he did it at Madrid. The whole club was a circus back then.
Chelsea second time around, he walked into a toxic dressing room. The same players, for the most part, did exactly the same thing to Antonio Conte a couple of years later. At United, he walked into a club that was just a mess, with a clueless Chief Executive and board who were intent on marquee signings rather than actually listening to Mourinho and building a team. Or did you not realise that Mourinho wasn't calling most of the shots on player incomings there? Nevertheless, I concede that his particular character would only have added fuel to the flames that were already burning at those clubs when he arrived.
Who knows what will happen at Spurs? Maybe it will all go up in flames there too. But you can't assume that that will necessarily happen just because it has happened a couple of times in the past. After all, would it have been right to assume that Pep wouldn't stay at City for more than 3-4 years because that was all he had done at any club previously?
