After winning the first leg, 2-1 in Mexico, the Brazilian club was favoured to win the second leg at home with ease. The Copa does not work on away goal advantage, so even a draw by Chivas would have forced penalties. And Chivas made a very bold statement with Marco Fabian executing a nicely done half scissor kick to give them the lead.
However, Rafael Sobis restored parity in the second half after Kleber centered the ball. Damiao Leandro subbing for Sobis made it two up as he stole the ball almost at the halfline and raced towards goal with Luis Michel unable to stop his shot. Chivas self destructed as Omar Arellano brought down D'Alessandro and was red carded.
Guiliano made it three as he niftily worked his way past a couple of defenders and toe poked it over the sprawled Luis Michel. Chivas in the dying minute made it closer with Omar Bravo pouncing on the rebound after Adolfo Bautista's free kick clanged off the upright.
Things got testy after Marco Fabian spat on an Internacional player and a melee broke out with players of both clubs engaging in some fisticuffs.
