Just as an aside of sorts – in case people are worried about that Pool 2 quota.
It'll be 64 starters, minimum, from that pool. Now, let's say this equals 7 teams – for good measure.
There will be a handful of Uruguayan vintages (both national and club) alone which will contain mostly Pool 2 players – where most of the players will be at least interesting in this context. That alone goes a fair way towards filling the quota – and then we haven't mentioned all the other vintages that all have several players of interest, nor all the Pool 2 players of unquestionable interest who weren't part of any high-profile vintages.
So, in short – coming up with four Pool 2 players should be a breeze.
