Barcelona's first Champions League campaign without Lionel Messi in nearly two decades may come to an end in the group stage if it doesn't find a way to beat Bayern Munich on Wednesday.
It would be the first time since the 2003-04 season that the Catalan club didn't play in the knockout stage of the competition.
Barcelona is second to Bayern in Group E, and two points ahead of third-place Benfica.
But a draw or a loss in Germany would allow Benfica to advance with a home win against already eliminated Dynamo Kyiv.
