Okay, stay with me on this one. So most people familiar with Argentine football will know that Argentina's league system is a bit of a mess and forever changing.
This year they've gone back to a system similar to the old one; a champion in the first half of the year and a champion in the second half of the year (Apertura and Clausura). It's a 16 game league system followed by playoffs twice a season essentially.
Well 4 days after the Clausura league portion had finished they decided to award a third trophy to the team that accumulated the most points across the 2 halves of the league season.
This crowned Rosario Central, the team Di Maria is captain of, champions. They also declared that the teams in the Clausura playoffs must give them a guard of honour despite the trophy just being made up there and then.
So first game of the playoffs they meet Estudiantes:
Estudiantes rightfully turn their backs acknowledging what a farce it all is. They beat Rosario and knocked them out of the Clausura playoffs.
The Argentine FA responds by banning all XI players for 2 games next season and bans the Estudiantes president, one Juan Sebastian Veron, for 6 months. Estudiantes are now threatening legal action.
