That wasn't the debate though, the debate was who was the better for us out of Moyes, Martinez and Koeman. It's not even a contest.
As for that last comment, we were fighting relegation and utter turd before he arrived. Still living in the 80's by any chance? It was only Moyes who actually gave us some credibility again after years of garbage.
As i was the one who posed the question about which of the three did the best, yeah it was Moyes obviously, but in no way shape or form do i regard him as a successful or even a manager who did good enough for us.
He initially did well, then stagnated - and stagnated when it was an era when other much worse teams went to difficult away games and won - we never did, other worse teams went and won trophies - we never did either.
You say he gave us back our credibility, I'd argue massively against that, he didn't - we where a struggling team when he took over and had been for years.
When Moyes took over at Everton - our last trophy was less than 7 years in the past, when he left it was 18 years in the past. Last league title was 15 years before, when he left it was 26 years in the past, he managed our expectations down at every opportunity - thats his style btw, first Manchester derby at united he referenced that City was where they aimed to be - putting united the reigning champions in a category below city by doing so, at Sunderland he immediately stated they where in a relegation fight at the start of the season - thus again downplaying expectations and ambitions.
At us he took over a fallen giant - which was still a big player - but one down at the time, he picked it up and then instead of puffing out his chest and pushing on, he spun the narrative that we where overachieving for a club of our size, that was all about Moyes bigging his 'achievements' up at the expense of the club, in fact the 'peoples' club line was absolutely cringe-worthy - it painted us as a local team for local people, at the exact same moment that the game was exploding across the globe, he also insulated this board against criticism by being fully supportive and in collusion with it's practices.
Some reckon he saved us from a potential abyss, and he may well have done that, but he was also instrumental in ensuring that our general perception now is not a fallen powerhouse of the English game, but is rather that of the best of the small teams who amount to nothing
