At the death, Cristian Campestrini gifted Carlos Fierro the winner as Chivas fought from two goals down to earn a stunning 3-2 victory over Puebla on Saturday.
The match had been billed as a battle between one of the best teams in the league, Chivas, against one of the worst, Puebla, but it was the latter who went ahead in the 26th minute when Federico Gonzalez squeezed a shot past the incoming Rodolfo Cota.
The visitors then took a shock 2-0 lead only moments later as Edgar Dueñas connected with an Adrian Cortes corner to double the lead for Puebla.
