According to u/TyCSports on Twitter, here’s what happened:

Rodrygo to Messi after Argentine team came out from the locker room: “You cowards.”
Leo Messi: “We are the world champions, why are we cowards? Look at your mouth.”

What I don’t get is why didn’t Scaloni substitute Messi? He was clearly injured.

Girona team’s coach/captain is the anime protagonist. They have plot armour in this season to win the league.

Chelsea doesn’t deserve to lose this game.
