Do City and Liverpool have a good structure though? City spent wild and never gained any stability till Pep arrived. Same with Liverpool until Klopp arrived. They had been in the wilderness for 30 years. Just like we had been for 26 years.
City had been after Guardiola for years by all accounts and despite their churn with managers they clearly had a plan with how they wanted to play and they won plenty of trophies before Guardiola.
Liverpool came very close to the league before Klopp arrived and did it playing great football. They again have had a reasonably solid plan for quite a while now.
Klopp and Guardiola are like the Messi and Ronaldo of football managers at the moment. You have those two then a massive drop off after. City will spend their way when Pep eventually decides to leave but Liverpool will tank when Klopp decides to go.
When Klopp and Guardiola move on I would bet my bottom dollar that neither of them will leave and their respective clubs says "what now". Bayern change managers reasonably regularly but they always have a plan. They would have seen the writing on the wall with Ole 2.5 seasons ago and aggressively pursued their chosen manager and sacked whoever was in charge when they could get him.
Who is realistically managing now that is at Klopp's and Guardiola's level?
Thats a very hard question to answer. Bayern are looking crazy good this season under Nagelsmann and being English we seem to struggle to give managers credit in foreign leagues because they are "weaker" than the PL.
Its a bit of a moot point though. Its a bit like saying "I'm going to stick with my morris minor because I can't have a bugatti". At this point we have one of the best squads around and a manager that isn't even close to be good enough for any PL side with any ambition. The gap in quality between our manager/coaching staff and the other teams with our resources is quite frankly mindboggling.
Ole got the job because he is old United and then he has given most of the high profile and important jobs surrounding the team to other members of the old boys club. This weird idea that because you were good at something means you can teach it makes no sense and no other industry thinks like this. Quite often the best people in a given field are awful at teaching and either need to be taught how to teach or take a very long time and put a lot of effort into learning it. Its something my partner constantly laments in the NHS. People who are good at their jobs are thrust into leadership roles and they are crap at it and aren't taught how to do it.
Getting your coaching badges is like learning to drive. It shows you have a vague level of competency but nothing more. I could get my coaching badges and that wouldn't make me ready to coach a PL team full of internationals.
