It's had this format for years I've been watching and following it since 1989. They invited MEXICO and USA and a few others in the past to make up 12 teams.
Format is ok, I like it that in the KO stages the game is 90 mins then penalties. Been a bit surprisedthat Colombia haven't really taken the tmt by the scruff of the neck as they came with a decent team. Think Chile v Argentina in the final.
Mexico didn't bring thier full team as they are playing in the GOLD CUP in July, thats on BT Sport I think. I also think that's why USA didn't want to play in it.
Me too cheering for PERU tonight.
They are planning a centenary tournament next year to celebrate the 100 years of the competition ,its due to be played in USA the first time a tmt has been played out side of South America. It will involve 16 teams; the 10 south American Nations and USA , MEXICO, COSTA RICA , JAMAICA with the other 2 slots going to teams that finish in the top 4 of the 2015 GOLD if they have not already qualified.
