Errrm, yeah?
Spurs had one top 4 finish in the PL era before Poch and he had a basic budget, in what world should he be challenging City, United and Chelsea to titles?
Dele just joined from Mk Dons
Kane returned from multiple mediocre loan spells
Lamela was a massive flop after they sold Bake the summer before
Players like Capou and Adebayor we’re regular starters for that Spurs side,his squad was full of mediocre talent.
Then his budget compared to those clubs was minimal, I’ll say it again he had no right challenging the way he did.
"Spurs had one top 4 finish in the PL era before Poch" is such a disingenuous way of putting it. It's also wrong. They had two top four finishes, both in the five seasons leading up to Poch's appointment. In these five seasons, their average league finish was 5th.
So clearly they weren't bottom half, nor did they have a god-awful squad. They had a lot of dross, sort of like us, that needed to be shipped out, but they also had a lot of quality. Vertonghen, Eriksen, Dembele, Rose (before he went to shit), Walker and Lloris were all key for him at some point. Kane hit the ground running when he was given a proper chance, so I'd include him as well. Chadli was also very good that first season under Poch, but went to shit afterwards.
Adebayor had been exiled under AVB, but Sherwood brought him back and I think, by the end, he was starting on merit. 14 goals and 5 assists in 25 games isn't a bad return, but he's also known for just deciding to stop giving a shit, so not a player you want to have to rely on. Capoue was never a regular starter for them.
As for whether they should be challenging us, City and Chelsea for titles? I mean, did they? They had that very good season where they finished second. At one point, towards the end, they were only 3 points off Chelsea. That being said, it was always Chelsea's title to lose, but they did push them until (almost) the very end, so I think it qualifies as a challenge. Aside from that, though? Us, City and Chelsea (and Liverpool) all went through periods of being gash while he was at Spurs, and Arsenal collapsed completely during his tenure. I think it's fair to point out that breaking into the top 4 had never been easier than during his tenure.
He's a good manager who did a good job at Spurs, but his job and his accomplishments tends to be blown way out of proportion. If you were to listen to his most ardent fans, he took a mid-table side and turned them into title challengers. He did neither of those things.
