How Buscuit with the size of a straw and two shorties not taller than 6'0 ft managed to dominate footy for a decade?

Because football is not like basketball where tall and strong is favoured.

golden state disagrees with you

i don't know about that. when did busquets ever dominate football. jordan dominated basketball, not scottie pippen nor horace grant, nor steve kerr. shaq dominated, not rick fox, nor robert horry. that's not to say they weren't important pieces in the team, but i'm not sure someone can be known as dominating the sport when you're not the best or second players on the team....just my two cents. now dominant in his position is entirely different.

Well, maybe because the height doesn't have anything to do with football skills and discipline?

It's like asking how the hell a team playing in red and blue was able to dominate football.

cost barca 2 points yesterday, he's no good.

Because he makes the best decisions in the smallest amount of time.
