FCB unbeaten in Lisbon
Three matches, one win, two draws: FC Bayern will take heart from a positive record in matches away to Benfica. After two goalless draws in 1976 and 1981 the German record champions posted a 3-1 victory in November 1995. The Bavarians also won the three matches in Lisbon against local rivals Sporting and Belenenses, by 5-0, 1-0 and 2-0 scorelines.
Only one defeat in Portugal
The Bavarians' overall record in Portugal is impressive. FCB have won five and lost only one match, with six games ending in a draw. In last year's quarter-final first leg the Munich men lost 3-1 away to Porto, but won the return by a whopping 6-1 scoreline and advanced to the semi-finals.
Home victory as a good omen
FC Bayern will be encouraged by another piece of good news after the 1-0 victory in the first leg. Munich have ultimately prevailed in all of the last nine European knockout rounds which began with a home victory from a Bayern point of view. The last time they were knocked out after a home victory dates back to the 2001/02 season, when Bayern lost 2-0 away to Real Madrid after a 2-1 home success in the Champions League quarter-finals.
Patchy recent record
Bayern's recent away record in European knockout rounds could do with a polish. FCB are winless in six, drawing three and losing three matches, with four goals scored and ten conceded. The last victory dates back to the 2013/14 season, a 2-0 success away to Arsenal.
Benfica strong at home
Beware! Strong hosts await the German record champions at the Estádio da Luz. Benfica have won eight of their last nine competitive fixtures on home soil. The record in European encounters with German sides is positive, with Benfica winning ten, drawing seven and losing two of the 19 matches and keeping a clean sheet 12 times. Benfica prevailed in all three of their last European knockout rounds which began with an away defeat.
Suspension risk for FCB foursome
Four Bayern players hope to avoid yellow cards as they would serve a one-match ban in case of another booking on Wednesday evening. Robert Lewandowski, Arturo Vidal, Joshua Kimmich and Juan Bernat would be onlookers in a potential semi-final first leg should they collect a yellow card. Jérôme Boateng, who has also picked up two bookings so far, misses out with injury. All bookings will be cancelled after the quarter-finals.
Dutchman in charge
Björn Kuipers from the Netherlands will be the man with the whistle for Wednesday's encounter at the Estádio da Luz. A good omen for FC Bayern: the German record champions have won the two group matches with the 43-year-old in charge, a 3-2 victory over SSC Napoli in November 2011 and a 3-1 victory over Manchester City in October 2013. Benfica by contrast have conceded three defeats with Kuipers on the pitch, including the 2013 Europa League final to Chelsea.
