Yeah, that was my initial thought as well: one of Mourinho's beefs with United is that they wouldn't spend in the transfer windows to get players he wanted. Does he have any knowledge of how Levy does business?
I get Spurs holding the purse tight given how much they spent to renovate WHL (Arsenal did for years after building their new stadium), but at the same time... you have a club that came within a win or two of winning the league in 2016 and a goal of winning the European Cup last season, on a squad entering what should be their prime years. Those sorts of squads don't come along often unless you're Real, Barca, Bayern, or (given their now bottomless pit of petro dollars) City*. You have to strengthen a side that good, while the silverware window is open. Given that the EPL has a top six, he also shouldn't have taken a CL place for granted.
*I think it is funny as hell that Pep is bemoaning a "thin" squad. scheiss off, City; I guess £2.5b doesn't buy what it used to.
