Also his comparison of EtH to Benitez is very generous, to put it mildly. Honestly, rather an insult to Benitez.
Yes, Benitez wasn’t the most likeable character and not up with the very best managers in the world. Yes we made fun of him here. But EtH’s achievements are nowhere near his. Not even close.
Benitez had a lot less resources than the top teams when he was managing Valencia and Liverpool, yet he won 2 La Liga titles, an UEFA cup and a CL whilst mostly being competitive (although behind the top) in the PL. He was also repeatedly sacked at other clubs quite early with the results usually being not that bad (at least vs EtH), so you might say that he did not have enough time.
Compare that to EtH who was at Ajax with a budget of multiple times more than the next club and at United who spent more than almost everyone under him (and allowed him to stay after 18 month of generally awful performances and results).
Yes, Benitez eventually declined and was constantly falling out with boards/players especially in the later part of his career. But Benitez is more like Tuchel level manager. Whereas EtH is Ole level manager at best.
