There are some fans who support teams cause their favourite players play in it. But it’s not as common to change the team you support cause your favourite manager left and personally I think that’s a fair metric too. I really like Jurgen Klopp’s style of play, if he left Liverpool and went to like Ipswich town or something then I would wholeheartedly support Ipswich town over Liverpool. Is that weird?
Uncommon, yes. But is it weird? No. Coaches/ Managers sometimes have that unique-ness in their philosophy. And sometimes they can bring a new, wholly different gameplan. Example, like you said is the Gegenpress (yes, Klopp wasn’t the first one who used this philosophy, but he definitely popularized it), Conte 3 ATB, etc.
Me personally? I’m watching Fernando Diniz currently, he has that unique close space football that reminds me of street football. Really captures the joga bonito in essence. Sure, the Brazil NT result isn’t that good currently, i think it’s because the player (or culture) doesn’t change yet. But yeah, if he takes job in europe, i can’t say that i’ll become X club fan, but for sure i’ll watch a lot of them matches.
Relationism, yeah. Renato Gaucho at Gremio has a similar philosophy to Diniz, too. I am enjoying this style of play coming back. It reminds me a bit of early tiki-taka. I think the main problem with Brazil at the moment is a lack of confidence. So many of the players were sloppy in the Uruguay match, Neymar getting injured was just the nail in the coffin. I haven’t been following Fliminense lately, but they have dropped down the table a bit, I guess this season has been a bit rough for Diniz in general. Let’s see how it pans out til Ancelotti becomes the gaffa.
