Argentinian giants San Lorenzo claimed a 1-0 win over Brazil's Cruzeiro in the first leg of the Copa Libertadores quarter-finals on Wednesday.

Edgardo Bauza's remain on the right track to win their very first Libertadores, as they celebrated the victory thanks to a 65th-minute header by Santiago Gentiletti, after a Nestor Ortigoza free-kick. It was a duel between the reigning champions of their respective domestic leagues.

Colombian defender Carlos Valdes told Fox Sports the victory was "a price for all the team's effort".

He added: "The Libertadores became an illusion for everybody in this squad. We took little lead and we are calm for that, but we'll try to win in Brazil because we have what it takes."

Cruzeiro forward Willian commented: "We tried, everybody fought a lot, but now we'll take the tie to the Mineirao and try to do a good game and win."

Nacional of Paraguay also edged a 1-0 advantage with a home triumph over Argentina's Arsenal. Derlis Orue netted the game's only goal with a right-footed strike after 35 minutes.

Nacional's win could have been wider but Arsenal keeper Cristian Campestrini saved a Silvio Torales penalty in the 22nd minute, when the match was yet goalless.

The home team coach Gustavo Morinigo analysed the victory telling Fox Sports: "We were looking for scoring and not receiving any. And we did both. This is a first important step. We know it means nothing yet, but it is important."
