Out of the mexicans playing in the MLS that play central midfield, it could be Dos Santos, Pizzaro or Eduardo López but it could also just be a Mexican from a different league travelling by LA...
And likely someone not getting much playing time of late, as reportedly a loan deal. Could be a younger player on fringes of 1st team football, MLS or Liga MX.
But Uffie has made it clear, they will be match fit, so they can hopefully make an immediate impact, regular season being 38% over before they play a game.
