Sounds like the 90's when Oasis would say they're the best in the world, "its not arrogance, we just think we're the best in the world" and they were, just like Vidal is now, still doesn't sound like something he would say lol
Yaya Toure is on Vidal's level imo, those two are the best at what they do, then theres obviously Iniesta, Silva, Pirlo, Schweinsteiger etc but those 2 stand out the most
Still its not bad to have a poll consisting of CM's who have different roles.There are players who play pretty much in similar positions as Vidal(ex : Modric) but their roles are different.
In his 'role' ,Vidal is the best but in his position ? Its debatable.
