What is the definition of World Class?
For different people it is different things, I say it's when a player is one of the best players for their position in the world, so the likes of Suarez, Messi, Ronaldo, Aguero, Iniesta, Lahm, Hummels, Neuer, De Gea.
Phil Neville won lots of medals, but he was never world class, then Shearer only has 1 medal, but he was world class, so it's not purely about what you win as some players are just lucky to end up in a team with some world class players like Neville did, it does not make him world class.
A team will always beat the a group of talented individuals, that's why RM struggle to win the league.
