I didn't see any comment on wealth in the post I responded to, but given the natural want of football fans and what they want to spend money on I did summarise the players Poch inherited who included 8 or 9 of his first choice 11 for much of his reign.
Poch was not one to rotate (if anything running players into the ground) so other than Son (the result of his agent trying to find a club willing to release Son for the Asian Games which if he won he got exemption from conscription) and Alderweireld, I'm not sure Poch bought any other first team players.
But Poch was also fully aware the stadium was going to be built, and had contractors not screwed up the wiring etc, he'd have had 2 years of New stadium income taking him into 3rd position in revenue terms : in fact when at Wembley for a full season Spurs were only a smidgeon behind 5 th place in revenue terms and even only playing CL at Wembley, gave a significant increase in revenue (and indeed prestige to draw players to Spurs, give club far more visibility/marketing opportunities.)
So in terms of revenues, for half Poch's reign at Spurs he was certainly not 'miles and miles' away from 5th place in terms of revenues.
Moving on to ManU, its a curate's egg of a position, in that its squad has some decent players in, and arguably other than its defence is not too far away from the standard he inherited at Spurs. And it still has far greater revenues than Spurs ever has had. Problem is Poch has not proved to be great at signing players at Spurs, so would he be any better at Man U
