Francisco "Panchito" Mendoza made his Chivas debut on Saturday in a 2-1 friendly win over Necaxa. Mendoza replaced Edgar "Tepa" Solis at halftime with the score at 1-1.
I'll have more info as it comes. I've only seen the lineup and a brief recap of the match so not sure where he lined up. Here's what the team looked like at halftime so I suppose you could piece together a formation based on this.
