Well, if its name be used, and any league qualifies, then I would say the champions league.\n\nit has the best of all the leagues across europe, all those champions fighting it out to see who will remain standing after the long group stage and then the pivotal knock out rounds.  Just look at the teams still in there (Arsenal, Barca, AC Milan) and you can see that, short of the World Cup and possibly the Euro competition, it is the showcase for players.
