Mexico and the United States; the two historical foes, face off in a friendly game on Wednesday, but nothing about the tie will be anywhere close to the sedate encounter you expect in international exhibitions.
And the rivalry has just been amped up another notch.
Liga MX - the top league in Mexican domestic football - side Puebla F.C have refused to release the two US internationals in their team that were set to play in the midweek encounter.
USA head coach Jurgen Klinsmann called up DaMarcus Beasley and Michael Orozco to his squad to take part in the game against 'El Tri' and was incredibly disappointed by their clubs actions, even taking to twitter to voice his disproval.
"We are very disappointed in the decision by Puebla," Klinsmann said in a statement. "When the match was scheduled, it was with the spirit that both teams would have access to their domestic-based players for what is a very important game for those competing for spots in the World Cup."
Midfielder Beasley is near enough guaranteed his spot in the squad for the World Cup in Brazil, while Orozco - a defender - would've been looking to make an impression on Klinsmann in what would've been only his 12th cap.
Puebla are in trouble in the domestic campaign at the moment and find themselves currently languishing at the bottom of the table and destined for a close date with relegation. Klinsmann understands why the team refused to release the players, but didn't agree with their actions, saying:
"Both MLS and most clubs in Liga MX honored that idea. While we understand their position, it's a huge opportunity lost for DaMarcus and Michael and doesn't contribute to the continuation of this respected rivalry."
This all means that the US are down to a roster size of 20 for the match, and that the game will be an all MLS vs all Liga MX encounter (except for Julian Green of Bayern Munich.)
