Xavi Hernandez faces his first critical test as Barcelona head coach on Wednesday night with the club at risk of failing to make the Champions League knockout stages for the first time in two decades.
A goalless draw at home to Benfica last month left Barca with their destiny in their own hands, but with a much trickier final game away to Group E winners Bayern Munich.
Spanish champions Atletico Madrid have their work cut to secure one of the five unclaimed last-16 tickets after three defeats on the spin, while all four teams remain in the hunt in an unpredictable Group G.
Bayern are one of three teams with a perfect record in this season’s competition, and Robert Lewandowski’s perceived Ballon d’Or snub may give the star striker extra incentive to prove a point.
Xavi suffered his first defeat as Barca coach on Saturday against Real Betis. He rested key players with a view to the game in Munich, where victory would guarantee Barca go through as runners-up in Group E, extending their 20-year run of reaching the knockout phase.
A youthful Xavi was establishing himself as a mainstay of the midfield when Barca exited in the first group stage of the 2000-01 competition.
Failure to secure maximum points would open the door for Benfica to pip them to second place, with the Portuguese needing to beat Dynamo Kiev in Lisbon.
Porto, AC Milan and Atletico will battle it out for the second qualification spot behind Liverpool in Group B.
