Your choice is clear but it's bullcrap to suggest being an assistant manager in a top flight league doesn't award you an advantage over someone coming into coaching years later no matter the entry level. When Pochettino was cutting his teeth in coaching Ten Hag already had way more experience and know how. Ten Hag has been dealing with the coaching side of the game at top flight clubs for longer than Pochettino. Since 2002 my friend. We can agree to disagree
Tell that to Phelan, Rui Faria, Meulensteen and countless others who wanted to make the jump from coach to manager and failed. Coaching while helpful, doesn't translate to managerial experience.
To me you are just clutching at straws because your precious Poch hasn't got any solid ground to stand on. You're trying to create this narrative that because Poch is younger and has less experience he has room to grow and improve, where in reality we already know what he offers.
His mentality is questionable, and every time a team required a rebuild/rebalance he failed spectacularly as shown by his time at Espanyol, PSG and later into the Spurs stint. He is only good if he walks into a team that is ready or entering it's peak such as Soton and early days Spurs. In a way he is a discount version of Pep, good coach, but nothing more.
Every single job he had comes with an asterisk next to it. Oh, he did an amazing job at Espanyol, but they were relegated. Oh he did an amazing job at Spurs, but eventually he got fired for poor results, buying poorly and he didn't win a trophy because "they are Spurs". Oh he is doing his best at PSG but Leonardo and player power, etc etc. Every single time there is some sort of excuse for his shortcomings. I get it if it's once, but after a while it's a pattern.
ETH on the other hand is an unknown quality on the top stage. But every single managerial job he had he over performed. No excuses, no relegations, no state backed oil clubs, no nothing. The man is clearly on the upward trajectory.
As a matter of fact ETH is everything you claim Poch is, but better. He is supper adaptable as referenced by his time at Go Ahead Eagles and Utrecht and his "unorthodox anti-dutch" tactics then he moved to Ajax and adopted the typical 4-3-3 and thrived with it. He is an amazing coach that improves his players massively and always improves youth players. He doesn't require a system or a DoF to be mega successful to do the signings for him as evidenced by his time at Utrecht. Nor does he require a perfect of perfect players.
The only thing you can hold against ETH is that he hasn't managed in a bigger league, but that could have been applied to any top manager before they got their break: Klopp, Sir Alex, Mourinho, Wenger, etc
Face it, your Poch is Arsenal/Spurs level at best. Top4 is all that he offers. And now that the league has become even more competitive and we are also in need of the biggest overhaul rebuild since Fergie retired, your logic is to hire the man who has shown 0 signs he can oversee a successful rebuild and curb player power.
I got that ETG is the shiny new toy, but Poch is a great manager on his own. His achievements with Spurs are remarkable.
He took a team that was finishing 5th on average, to a team that was finishing 3rd on average while United and Pool were AWOL and all of that on a bigger net spend than Chelsea while having prime Kane, Son, Vertoghen at his disposal. Wow, remarkable indeed.
