( CNN ) -- Brazilian club Corinthians are champions of South America for the first time after a 3-1 aggregate defeat of Argentina 's Boca Juniors in the final of the Copa Libertadores . After a 1-1 draw in last week 's first leg in Buenos Aires , two goals from Brazil-born Qatar striker Emerson gave coach Tite 's Corinthians a 2-0 second-leg win in Sao Paulo . Wednesday 's historic win over six-time champions Boca ensured Corinthians ' qualification for December 's FIFA Club World Cup in Japan . It also means South America 's premier club competition has been won by a Brazilian team in each of the last three years , following on from Santos in 2011 and Internacional . Are FIFA 's world rankings fit for purpose ? `` I am very happy because we know the history Boca Juniors have in worldwide football and in the Copa Libertadores , '' Emerson told Fox Sports . `` Our crowd represents 33 million fans . Since this year 's Libertadores started , we have dreamt of clinching the title . We were all in need of this achievement . '' Corinthians ' undefeated campaign was powered by five goals from the 33-year-old Emerson , as well as four goals from attacking midfielder Danilo -- who won the title with Sau Paulo in 2005 . On a disappointing day for Boca , midfielder Juan Roman Riquelme also announced Wednesday 's game would be his final appearance for the club . The 34-year-old began his career with Boca before spending six years in Spain with Barcelona and most notably Villarreal . The former Argentina international returned to Boca in 2008 , helping his first club to two domestic titles to go with his three earlier Libertadores successes ( 2000-01 , 2007 ) . `` This afternoon , I spoke with the president and informed him that I would not continue , '' Riquelme told reporters . `` I am very grateful to the club and the team , I know I am , but I have nothing left to give the club , I 'm empty . The relationship I share with Boca is great , I 'm a fan of this club but now I have reached the end of the road . `` Now I just want to go home , have a barbecue with my friends , see my children and greet them . All I ask is for forgiveness from my child that I could not win the cup again . ''
