But some can see that he is learning absolutely nothing from his many failures this season, with a squad Poch would have killed to have.
Quite frankly, the rest is a matter of opinions (and yours are always worth reading) but I don't see where you're coming from with that last sentence. Pochettino had one of the best defensive partnership in the world in Verthonghen and Alderweireld, Walker (I don't think there's a single manager in the league who'd choose Aurier or Doherty ahead of him), Dembele and, more importantly, Eriksen, who was considered as one of the best playmakers in the world at this time.
Reguillon is probably a better player than Rose at his peak and you could make a case for Hojbjerg to get in the starting XI but Pochettino would have been an idiot to kill to fill two position while losing arguably two or three world-class players.
That's what makes all the current frustration vastly irrelevant to me at the moment. We blew it the year Leicester won the league. That title was ours for the taking and for many reasons, we couldn't make it happen. There's no way this squad is any better so the only logical argument for considering us title contender would be to accept that Mourinho is a vastly superior manager. I don't think that's the case. Pochettino was coming to the end of a cycle - which is something that happens to every manager when they don't change clubs every couple of years. That's the nature of the modern game but expecting Mourinho to work miracles is just setting oneself for disappointment.
Then surely we're in trouble because this is no way to play football and ultimately is the same blueprint that lost him his last two jobs in this country?
I think that's the bottom line. If you don't like the football on offer, individual results are pretty much irrelevant. That's something I can understand. It's slightly different for me because I'm an armchair fan. It doesn't mean I like Spurs less than anyone else on here, but I haven't been to a game in 10 years or so. The investment isn't the same when you spend most of your day going to and from the stadium, chanting your lungs out, paying for a season ticket, etc.
Of course, nobody is able to do that at the moment, but I'd understand someone telling me they don't want to invest that much time and energy to see a boring win. I'd say it's slightly different when you're watching on TV because you can take an interest in other things: opposition players, positioning, stats and so on. And if the game is really boring, I feel it's easier to let your mind wander when you're sitting comfortably at home.
As it stands, the balance between results and entertainment remains decent enough for me, because I know the Mourinho era, like all others, is a temporary thing. If his tenure turns out to be a stepping stone then it would have been worth it, for me. But that's something nobody can tell until the end of the season. As things stand, it's likely that our entire season will depend on a couple of games...
