Jules Kounde was the unlikely hero as his double powered Barcelona to a 2-1 victory over Eintracht Frankfurt to boost their Champions League hopes.

Ansgar Knauff fired the visitors ahead on Tuesday, only for Kounde to inspire a second-half turnaround to move Barcelona up to 14th and just two points shy of the top eight.

Robert Lewandowski saw an early strike ruled out for offside in the build-up against Raphinha, before Gerard Martin stung the palms of Michael Zetterer from range in a one-sided opening.

But it was Eintracht who struck first against the run of play when Knauff beat Alejandro Balde to Nathaniel Brown’s throughball and steered into the bottom-right corner in the 21st minute.

The visitors almost doubled their advantage on the stroke of half-time, though Ellyes Skhiri’s first-time effort flew just over the top-right corner.

A half-time change made the difference, however, as substitute Marcus Rashford curled in for Kounde to head home in the 50th minute.

Defender Kounde then struck again just three minutes later, rising the highest to nod past Setterer after a teasing Lamine Yamal delivery from the left-hand side.

Ferran Torres whistled a fierce effort wide as Barcelona sought to put the game to bed, though Eintracht could not mount a late comeback regardless.
