I think he was just slightly offside by his left foot. Idk man even then it was a close call because the angle they showed didn't fully show the Leon player's legs.
Hasta saque la regla, los estaban habilitando. You're making it seem like Tevez against Mexico in 2010.
I think he slipped and hurt himself so they subbed him off. He was limping so they told him to get on the cart.
