Title holders Manchester United beat Italy's Inter Milan at Old Trafford 2-0 to reach the quarter-finals, while Arsenal had to wait until the penalties to finally get the better of Roma. Elsewhere, Porto qualified after drawing with Atletico Madrid.
Manchester United set a record of 21 matches unbeaten in major European competitions with their 2-0 home win over Inter Milan in the Champions League on Wednesday.
United, who won their last-16 tie 2-0 on aggregate, broke the record they shared with Juventus, who went 20 matches unbeaten in the Fairs Cup/UEFA Cup between 1970 and 1972.
The English champions' last defeat in Europe was 3-0 away to AC Milan in the semi-finals of the 2007 Champions League.
United also extended their unbeaten home record in the Champions League to 19 matches, winning 15 of them. AC Milan were the last team to beat United at Old Trafford in the competition, 1-0 in the same round four years ago.
Roma sink at the Stadio Olimpico
Max Tonetto missed the crucial spotkick as Arsenal beat AS Roma 7-6 on penalties to reach the Champions League quarter-finals after the Italian hosts won the second leg 1-0 on Wednesday.
Roma made it 1-1 on aggregate after nine minutes when defender Juan, who later went off injured, slammed in at the far post after Arsenal had allowed Francesco Totti's ball to run across the box.
The home side also had a strong shout for a penalty when Marco Motta went down under pressure from Gael Clichy just before halftime.
Arsenal had a few decent chances in normal time but neither side came close in a tired extra period.
