Well said. If Moyes cant handle the step up to a massive club - what makes anyone think that these two can? Moyes has a better track record than both of them over a longer period.
A lot of people seem blinded by the suggestion that United are now some kind of "West Ham-esque punt it wide and long" team which now seems to be accepted as fact by a lot of people - as if we were playing lie Barcelona last year under Fergie.
These fellas might prove to be every good managers, only time will tell - but you have it spot on. This suggests an "anyone but Moyes" approach from some fans which is bizzare.
It's really not though, it's just the fact for others, similar to myself... we've sat there over the years watching somewhat impartially, we look at the way Martinez for example sets his team up and how he tries to win games, playing technical football being better suited for a top club, than Moyes approach of being solid and tough to beat which is far more suited for a midtable team.
At Everton, they struggled a touch when up against other solid teams, where they had to come out of their comfort zone and press for the advantage, we've clearly seen it with United, the most obvious candidate being Fulham where Moyes has RVP, Rooney, Januzaj and Mata and co. and all he can come up with was percentage balls slung into the box, give Martinez those type of players and watch our football take off.
Martinez's Wigan were relegated after 4 or so years, (winning the FA cup along the way) but the Cafe's mancrush Klopp achieved the same feat in his time with Mainz, similarly the way Martinez attempts to play football isn't suited for a lesser talented, struggling side yet stuck to his principles, the poorer teams in our league which perform best of all are usually overly solid, horrible teams to watch like those under Big Sam and Pullis, their tactics are suited for that type of role and nobody would entertain them being a top 4 manager because their "football ceiling" isn't as high as a Martinez type.
Those other "lesser" sides who try and play football usually end up getting relegated, such as Reading last year, compared to a "solid" Stoke/West Ham, so in that respect, Martinez was always likely to struggle with Wigan, it doesn't automatically mean his potential pedigree for coaching a top side isn't abundantly higher.
