If I were to just type that United are playing badly some United lifelong supporter is going to barge in whose father was a United fan, whose grandfather was a United fan, whose great grandfather was a United fan and tell you that the stats show that Ten Hag has scored more points than SAF or Klopp or Mourinho or whoever. When I see such people and there are millions of them worldwide and especially in the UK I automatically wonder if you have to be low IQ to be a football fan. You don’t need stats to tell you that United are terrible. If you have eyes you can see that they are scrapping through and not heading in the right direction. On the other hand if you can understand football you could have figured out that Chelsea on the other hand for all their defeats are headed in the right direction. They might be down in the points table but there is a plan that is slowly working at Chelsea. If you just give it time they will be in the reckoning sooner or later. How is something as basic as this not evident to people.
I have 30+ yo mates who have never been a gamer and still technically know so little about their biggest hobby (footy). Just look at channels like Sky and how the most stupid failures of managers are now pundits criticizing the very best active managers using similarly stupid superficial logic. Football is getting more complicated and many are just too damn stupid to keep up. Specially in recent years, it’s been more obvious than ever. The best keepers or strikers of an era say shit like “keepers shouldn’t play it short by feet” or “strikers shouldn’t tire themselves working too muchnfor the team”…
TLdR; In all fields whenever there is a relatively sudden evolution, there are some who can’t handle it and get stuck in the past. Football used to be an easy to grasp hobby for all ages, it’s only natural that number is quite larger here.
