I agree and I have said that they have done extremely well but when I look at what is required for United, he isnt it.
Whilst he has done really well, being defensively solid is a requirement for a top tier coach.
I think McKenna can be a good coach, but that doesnt mean he should manage United based on what he has done at Ipswich.
At the moment, we need a manager with a big personality.
I agree that he isn't right for United. I think we need a manager who has spent some real time in a top league and has a very clear and tested vision of how he wants his team to play. By the same token, standards at United are at an all time low in some respects. Amongst the hierarchy, I think we have the clearest vision we've had in a long, long time, but on the pitch we just extended a manager that finished 8th in the League, and let him go multiple weeks in the bottom half before we took action. That means that the new manager coming in has a very low bar to clear. In some ways that means we have an opportunity to go after a bold, young coach because their initial "success" will be all relative to what came before. Despite the 14th place, the home fans had yet to really turn on ETH - which is frankly incredible - and of all the top jobs out there, I think United is the one with the most upside. Anyone getting a top six finish, will automatically be seen as a vast improvement. As much as United can ever be "low pressure", this is as low pressure as United will ever get.
Thomas Frank seems to be the favourite right now, and as a very pragmatic and flexible coach, I think he will do okay. He will drill the fundamentals into the players and I think we'd become much harder to beat, much tighter defensively, and across the board more organised. I don't think I've seen anything from Frank that suggests that he'd be a revolutionary appointment. I don't see a tactical visionary. But I do see someone that will create a compact, hard working side that plays to it's strengths, instead of trying to emulate what people expect of him. That might be exactly what United need right now. He has finished 13th, 9th and 16th with Brentford in the PL, albeit the last one without his top scorer who was banned for the second half of the season. It doesn't look spectacular, but it's been done on very limited resources, with a very limited playing squad. How he deals with the bigger egos in the dressing room etc., would be interesting; but I do think the squad is full of players that would suit Frank's style quite well. De Ligt, Martinez, Maguire, and Yoro is an excellent set of center backs for him, in midfield he obviously knows Eriksen well, and I think Mainoo and Ugarte are tailor made for his style of football. I can also see him restraining Casemiro to focus on doing what he's good at, in the areas he's most familiar with. Rather than the marauding nonsense we've seen the last 18 months. I can see him getting plenty out of Hojlund, and under Frank I would not be surprised to see Fernandes shift wider right, and focus on getting quality deliveries into the box.
Amorim and Nagelsmann would be much more adventurous appointments. Young managers still making their way in the game, but both with a lot of credibility in the game. However, I can easily see United being the breaking of them. The squad is ingrained with bad habits, and I don't think either have been tested to the level the United job would test them. Nagelsmann perhaps at Bayern, but I think that's nothing like the environment he would face at United.
The only coach I see out there that actually has the experience, strength of character, resilience, and pedigree to check all the boxes as a transformative United leader, is Emery. But I don't see any chance whatsoever in that happening.
