Despite Racing’s suspect defence providing an early scare, Diego Cocca’s side booked their place in the Copa Sudamericana last 16, coming from two-down to earn a 3-2 win over Independiente Medellín.
Trailing 3-1 from the first leg in Avellaneda, the Colombian side struck twice in the opening 25 minutes thanks to two close range finishes by Leonardo Castro and for a moment were in the driving seat to progress.
However, a Diego González header on the stroke of half time swung the tie back in favour of Racing.
With the visitors now on the front foot, youngster Maxi Cuadra equalised on the night from the penalty spot and as the home side lost their cool with three red cards, Brian Mansilla wrapped up the tie with a late third.
Racing will play Corinthians in the last 16 after the Brazilians.
Arsenal de Sarandí will not be joining their compatriots after conceding a late goal to Sport Recife.
Humberto Grondona’s side reversed the two-goal first leg defeat with close range finishes by Juan Brunetta and Rodrigo Contreras either side of half time. However, with penalties looming the visitors snatched the tie when André tapped in a vital away goal.
Given Arsenal’s struggles domestically it is hardly surprising to see their Copa Sudamericana journey come to an end and it will be Sport to take on Ponte Preta in the last 16.
Arsenal 2 – 1 Sport Recife (AGG 2-3)
Independiente Medellín 2 – 3 Racing Club (AGG 3-6)
