As we all heard last week, Alex Ferguson declared that he had four world class players during his long and successful time in charge of Manchester United.
Of course, the headline-grabbing part of that pronouncement was the absence of Roy Keane from that list.
The former United and Ireland captain won't lose sleep over it, one would imagine, but the term "world class" is interesting in the sense that it is often used by pundits, fans and commentators, yet remains totally undefined.
On this week's Team 33, we were joined by old friend of the show Eduardo Alvarez of ESPN and Radio Marca to muse about what we all think the term means and who it really applies to.
Of course, we can all agree that Lionel Messi and Cristiano Ronaldo are world class or beyond, but it's the tier below whose status is less certain.
So was Roy Keane world class in other eyes other than Ferguson's and is world class more a question of ability or achievement?
