"Why do Spurs fans always think we have the best X in the world for most categories?" - No mention of a world XI, let's see if we can avoid trundling into yet another "Everyone explains what their own arbitrary definition of what world class means without budging, rendering any discourse completely pointless" chat, it's summer and we're bored without football, but not THAT bored hopefully.
Over the years, it's been Lloris is the best keeper in the world...Toby is the best ball playing CB in the world...Dembele is the best midfielder in the world....King would've been the best in the world yada yada yada
TBF it's often stating that the aforementioned players are the best in the league as opposed to the world so I'm perhaps indulging in a little hyperbole. But the key is it's mainly opinions that you'd only hear from Spurs fans. I'm not saying we haven't had some great players. It's hard to not make the case that Walker was one of, if not the best RB in the league for quite some time.
I'd agree that Son is an elite player, but stating an opinion that he was the best finisher in the world like it's a fact would be where I'd draw the line. Cases to be made for Bale and Modders being the best in the world for certain things as they went and did it on the biggest stage.
