I wonder how much the effect of the European mega-leagues, especially the Prem, sucking up global talent has levelled the field. The top talent from every nation gets thrown into a small number of melting pots where they're exposed to other top players and the best coaches. The Prem comes out top, with Manchester City the most represented club. There's a good argument to be had about the small number of English players in the top clubs vs the benefits of those players working with some of the best coaches and foreign players, but I think we're seeing at least some of the benefits this time around.I don't know if it's a blip but have standards levelled in world football? The tournament has been invigorated by many of the so-called big teams under-performing and getting knocked out.
It's been refreshing.
Anyways, here are the stats....
