Yes they played beautiful and dominant football that 2016/17 season and it was the third straight season in the top three playing exciting football. That season was simply the pinnacle of that era for Spurs.
Think you're vastly overexaggerating their attractive football with your praise. They played nice, decent football, but I'd never have call their football "dominant". They were high pressing, kept possession well, but never had control over the game such as Guardiola or Klopp's teams. I always found them chaotic in their play. You talk as if Tottenham dominated the league in 2016/17, but the reality is that their goal difference was only +8 over Conte's Chelsea, who is described by people as a conservative, defensive manager. Now I've disagreed with that, but surely we'll both agree that Conte is not as attacking manager as Klopp or Guardiola are.
Asid efrom that season, the rest of his seasons have not been even remotely as "impressive". in 2014/15 the GD is +5, in 2015 and 2017 it was +34 and +38 respectively - surprisingly a worse GD than us under Mourinho. in 2018 it was +28 and in 19 it was just +14. This is a very, very bad trend that we're witnessing here.
So I think we can put the myth of Poch's ultra exciting and dominant football to rest. He had one very good season, but aside from that Spurs have largely been above average and that's it. Nothing really spectacular. In comparison, Ten Hag's dominant performancce in the league is as follows:
in 2017 it was +56 (shared season with a sacked manager). in 2019 +86, in 2020 +45 in 26 matches (season cut short because of COVID, from what I remember), in 2021 +79, rigght now with 26 matches played Ajax has a GD of +66. Now that is league dominance. Before him Ajax meagered around a 30-50 GD, only once hitting 60.
See the difference between the two managers?
Outscoring everyone else in the league and having the best goal difference is literally being dominating. Spurs did play beautiful football. It's true to me, not to you, it's not objective is it? How long did it take Klopp to win anything of note with Liverpool? He won the league title in 2020 after being there 5 years but he got the backing he needed for instance.
That's not true. Dominating would be winning actual titles, something Poch still hasn't done. Dominating would imply Spurs were title challengers, they were not. You can't say he dominated the league or anything like that when he achieved nothing really of note. It took him 3 seasons to win the CL with Liverpool with an obvious progress along the way. What... um, did Poch win in 5 years at Spurs?
The PL is very competitive, something Ten Hag hasn't experienced. Do you think he'd have went further and won something at Spurs if he coached them? Do you think he'd have handled the internal adversity of working with Levy better than Pochettino did?
So is the Eredivisie. You're making a mistake thinking just because the Eredivisie is a poorer league, it isn't competitive. Ajax hadn't won the league for 4 seasons prior to Ten Hag's appointment. And I'm sorry but when Poch came to Spurs the league was in a big transitional period, ripe for the taking. SAF had retired, Klopp and Guardiola still hadn't come in (and they had their transitional seasons, too), Arsenal were still wallowing in midtable and Chelsea went through a couple of interims. He did a decent job, but let's not pretend the league back then was at a lower level than it is currently. Let's not forget that Leicester won the league during that time, too.
As far as how Ten Hag would do a Spurs, there's no point in talking in "ifs". Neither you or I will ever know the answer to that. Or anyone in the world, for that matter.
We'll never know, but Poch not winning under those constraints is not what we should be focusing on, his feat in itself to catapult Spurs in the manner he did is worthy of praise. His accomplishments at Southampton, making them one of the most exciting clubs to watch in the league in his few years there is something worthy of praise as well. His influence on English football is something worthy of praise and not something to be glossed over or go unacknowledged.
Okay, I think this heap of praise on Poch over his wrok at Spurs is grossly exaggerated. Yes, he did a good job, but come on - this isn't Fergie at Aberdeen or whatever. He took over perennial top 4 contenders and made them a consistent top 4 team until he was sacked. Okay, that's a good job, true, but it isn't amazing or something. He didn't win the title with Spurs, he didn't win the CL with Spurs or any major improvement in the league for him to get this praise like he was working miracles.
He did a good job, but that's it. Nothing out of the ordinary.
Poch is a risk indeed, but for me he's less of a risk than a manager who's never managed in a top league. Crystal Palace found that out with Frank De Boer even though he had a previous dominant spell at Ajax, winning four league titles in a row. Dortmund found that out with Peter Bosz when he made the step up from Ajax after taking them to the EL final with that exciting young team united beat in 2017 (he was replaced at Ajax by Ten Hag of course). Winning the Dutch league doesn't mean shit, with all due respect. Am I impressed by Ajax's brand of football under Ten Hag? Very much so! I still think Poch is the better candidate
Neither Flick, nor Guardiola, nor Zidane, nor Nagelsmann or whoever needed to prove themselves before taking over a top club. They just did it because they had the qualities. If we wait on managers to prove themselves, we'll miss out on every great manager in existence. These same arguments were used on Klopp when the discussion for him being our manager came up a long time ago.
Even in press conferences Ten Hag speaks like a United manager in the mould of Fergie, Poch speaks like a manager in the mould of Ole. As far as your example with the managers you've listed, none of them ever showcased the dominance that Ten Hag's teams do. Ten Hag also hasn't been at Ajax only, he has done a very good job at other clubs and teams, too.
So far Ten Hag has achieved remarkable success at every club he has been. Okay, we can agree the level he has been in has been much smaller, but he's been impeccable everywhere. In contrast, Poch has been sacked from Espanyol, Tottenham and now would be from PSG, too. Three clubs in a row. Not a very good trend. Do we really need a manager who can get us top 4 for a few seasons before inevitably shit hits the fan, everything collapses and we're right back to square one? We've had that with Jose and LVG, hell Ole ,too. If the goal for this club was to just get top 4, maybe we should have just kept Ole.
