( CNN ) -- Two of South America 's most famous clubs reached the semifinals of the Copa Libertadores after late drama in their last-eight matches on Wednesday . Argentina 's Boca Juniors , six-time winners of the continent 's premier club competition , snatched a 2-1 aggregate win over Brazil 's Fluminense thanks to a 90th-minute goal from Uruguayan Santiago Silva . Having lost the first leg 1-0 in Buenos Aires , Fluminense leveled the tie in front of their own fans when Thiago Carleta 's deflected shot found its way past Boca goalkeeper Agustin Orion . But Silva 's late strike sealed a 2-1 aggregate win for Boca and Julio Cesar Falconi 's team will play Chile 's Universidad de Chile or Paraguay 's Libertad in the semifinals . That tie is level at 1-1 ahead of Thursday 's second leg at Universidad 's Estadio Nacional in Santiago . Who are European football 's `` Most Valuable Players ? '' Fluminense 's coach Abel Braga was disappointed to see his team eliminated after dominating the second leg . `` It was incredible . Our keeper had a very quiet night , they only attacked one time and it was a goal , '' Braga was quoted as saying on FIFA 's official website . In an all-Brazilian tie , Corinthians defeated Vasco da Gama 1-0 on aggregate as the Sao Paulo club continued their bid for a first Libertadores crown . Vasco , based in Rio de Janeiro , went close on several occasions before Corinthians -- one of Brazil 's most successful clubs -- delighted home supporters with Paulinho 's match-winning header after 87 minutes . `` This qualification was the merit of the entire team , and I think it was well deserved , '' said midfielder Paulinho . `` Now , we have to rest and start thinking of our next rivals . '' Corinthians will play defending champions Santos of Brazil or Argentina 's 1994 winners Velez Sarsfield for a place in the final . Velez hold a slim 1-0 lead heading into the second leg in Sao Paulo .
