I still think they should appeal the Wes red, I didn't see anything on camera that Wes did in particular any differently than anyone else.
Sergino has to be smarter about being goaded into a red, though.
The referee completely lost control of the match after the 3rd goal and should never work one of these games again. Punish Mexico for gooning it up right away, hell, give them 2 reds at the beginning of that shitshow, and it doesn't devolve the way it did.
