Thank goodness for Jonathan Requena as far as San Lorenzo are concerned, as it is only due to the ineligible midfielder featuring for Chilean club Deportes Temuco in the first leg, that has seen Los Cuervos progress to the Copa Sudamericana last 16.

Defeat in the Nuevo Gasómetro three weeks ago was a shock and had left Claudio Biaggio’s side a lot to do in Chile but when it was realised that Requena had been listed as part of Defensa y Justicia’s squad earlier in the tournament, San Lorenzo were able to lodge a complaint to CONMEBOL.

Despite the oversight and Temuco feeling a sense of injustice after their historic result, the rules were clear and San Lorenzo’s 2-1 defeat was suddenly a comfortable 3-0 win.

A tense atmosphere in Chile saw plenty of aggression towards San Lorenzo and the visitors were firmly second best once again on the pitch.

Only an outstanding goalkeeping display by Nicolas Navarro ensured that the three-goal margin was enough. After a string of fine saves and Temuco hitting the crossbar, the keeper was eventually beaten. However, Matias Donoso’s header coming in stoppage time left no time for the hosts to comeback.

San Lorenzo didn’t deserve it but book a place in the last 16 where Nacional lie in wait.
