Corinthians progressed to the quarter-finals of the Copa Libertadores on Tuesday without the injured Willian, going through 6-5 on penalties after two goalless legs.

After Boca scraped a draw in the first leg in Sao Paulo, they were given a chance to take the early lead from the spot, after a VAR intervention penalised Raul Gustavo's errant elbow.

Despite sending Cassio the wrong way, Dario Benedetto smacked his effort against the frame of the goal, critically maintaining parity in the tie.

The 32-year-old had the best chance of the second half for Boca as well, but his chip in transition floated just over when put through by Sebastian Villa.

In the shoot-out, back-to-back penalty saves from Agustin Rossi were not able to save Benedetto, who skied his second penalty before Gil eventually put the Timao through.

Hulk sends CAM through

Atletico Mineiro left it late but secured their progression to the quarter-finals, defeating Emelec 1-0 in Belo Horizonte to go through 2-1 on aggregate.

Antonio Mohamed's side struggled for significant portions of the first leg but dominated possession and territory in the return, with 21 shots to six on the night 

Hulk's 79th-minute penalty ultimately proved the difference, calmly slotting past Pedro Ortiz.

Romulo salvages draw and progression for Athletico-PR

Athletico Paranaense snatched a late 1-1 draw in Asuncion, advancing to the quarter-finals by winning 3-2 on aggregate.

The Paraguayan champions forced themselves level on aggregate through veteran Roque Santa Cruz in the fourth minute of first-half injury time, scoring via a wonderful solo dribble and finish.  

When the tie looked set for penalties, Romulo dramatically secured passage for Luiz Felipe Scolari's side, picking up the rebound from his own header to score in the 90th minute.

Boca Juniors claimed an important result in their first-leg tie against Corinthians in the last 16 of the Copa Libertadores, holding on for a 0-0 draw in Sao Paulo on Tuesday.

Corinthians dominated proceedings at home but were not able to capitalise, with Roger Guedes also failing to convert from the penalty spot with the interval approaching.

It would have been a deserved lead for the Timao after a positive opening 45 minutes, but Guedes was brilliantly denied in the 43rd minute by Agustin Rossi, who guessed correctly and quickly reacted to save.

The home side's best chance in open play fell to Giuliano after a mazy dribble into the penalty area from Willian in the 46th minute, but Marcos Rojo scrambled to quell the danger.

With Exequiel Zeballos and Dario Benedetto struggling to have a tangible impact, coming back to Buenos Aires for the second leg with parity intact is a positive for Boca, after also failing to defeat Corinthians in their two Group E games.

Ortiz denies CAM smash and grab

Emelec will have to progress past Atletico Mineiro in Belo Horizonte after only managing a 1-1 draw at home in the first leg.

As expected under Antonio Mohamed, CAM primarily looked to absorb pressure, and they scored against the run of play in the 16th minute. A spectacular first touch from Hulk to bring Everson's hoof under control put Ademir through, and he calmly converted past Pedro Ortiz.

Emelec captain Sebastian Rodriguez deservedly got his side back on level terms in the 58th minute, but CAM had a penalty of their own with two minutes of regular time remaining. Ortiz stood up this time, though, denying Hulk what would have been the winner.

Athletico-PR take first leg

Two first-half goals from Athletico Paranaense allowed them to secure a 2-1 win at home to Libertad in Curitiba.

After confirming Fernandinho's signing from Manchester City, Luiz Felipe Scolari's side were characteristically solid defensively, but only after they hit the lead a second time.

Vitor Roque put the hosts ahead in only the sixth minute but the Paraguayan champions equalised through Hector Villalba in the 20th minute. Athletico PR restored the lead 12 minutes later, with Nicolas Hernandez scoring the eventual winner.
