It's the baldness obviously. Feels like there's just an infinite supply of Dutch coaches who are Guardiola/Cruijff/Van Gaal adepts, and whether it's Bosz, Slot, Ten Hag, or Pascal Jansen at AZ now, or Frank de Boer before his hair transplant, they all share one common physical trait.
Seriously though, I'd be interested as well to see what would happen with Ten Hag at a bigger club. I've had many discussions on here over the years about Guardiola, and I've always been of the opinion that his tacticism is extremely overrated. Not that he isn't a great tactician, of course he is (even though his pointless tinkering has also costed him on quite a few occasions). But I always provocatively said to people on here who acted like Guardiola invented football himself, that at any given point you can select ten other Dutch or Spanish coaches who can set up a team exactly like Guardiola does and are tactically as strong as he is.
Whether it's guys like Bosz or Ten Hag or a new guy like Arne Slot, or someone like Giovanni van Bronckhorst, who of course played under Wenger and won the CL with Barcelona in 2006, and then won the Eredivisie with Feyenoord as a manager often playing a typical 4-3-3, using a lame duck type of midfielder with Jan Arie van der Heijden as a CB because it's always about building from the back and posession orientated football first and foremost with those type of managers.
I just feel that with Guardiola his tactical nous is way overrated, while at the same time his people management skills are extremely underrated. And also in general at the highest level of football it's so much more about people management, managing the dressing room, really inspiring players, keeping your authority than it is about pure tactics. I mean didn't City get knocked out of Europe while Guardiola
kept guys like de Bruyne on the bench (click) in crucial CL matches without creating a mutiny?! That's insane when you think about it.
Similar how he has casually benched none other than Aguero because Jesus fitted his high pressing plan better against certain opponents, it's remarkable how players seem to accept that from him, only the truly great managers can make such decisions and get away with it (remember when even a guy as succesful as Mourinho benched Pogba against Sevilla in the CL, that basically was the interlude of the end of his time at United). Nearly every player I've heard about Guardiola, other than Zlatan of course, talks about how inspiring he is, what a fantastic leader, stuff like that. At the same time while obviously he has implemented very cool tactics and made his teams play in both a revolutionary tactical way as well as in a traditionally Cruijffian/Barcelona way, he didn't exactly teach guys like Xavi and Iniesta how to play tiki-taka to throw out a nice cliché, yet plenty of people obviously talk about the man like he did.
I don't know if you saw the recent Ruud van Nistelrooij interview with Rio Ferdinand, he talked about how Fergie benched him for the final match of his first season while he still could've won the golden boot, only because United didn't win anything that year. Only the real great managers can make such decisions without losing authority, and motivating top players, superstars in their prime even more. And I just don't think Ten Hag at this point in time has the status or the personality in general to pull something off like that, and I do think that's the type of skill you need as a manager at the very highest level. I mean, he could do well at Bayern I think, but can I see him benching Lewandowski for a more energetic high pressing striker at the start of the season because that would be better for the team and put everyone on edge, extra motivated and sharp? I think he would lose the dressing room within weeks if he did something like that. You saw it with Frank de Boer too at Inter, that dressing room ate him alive, even though he was a pretty well respected player and coach before that.
So yeah that's a bit of a longer version of what I was trying to say in earlier posts about Ten Hag.
