The Copa remains Barca's most realistic chance of silverware this term, and Ronald Koeman's first trophy at the helm, but they will have to do it the hard way after slipping to their first defeat in 90 minutes since December 8, a run of 16 matches across all competitions.

Kounde got the first goal with 25 minute played, the 22-year-old centre-back charging forward to great effect a few moments after going close from just outside the box.

Barca dominated most of the second half with Sevilla seemingly happy to play on the counter, but the visitors could not breach Yassine Bounou's goal and Rakitic finished them off on the break as Julen Lopetegui's side made it seven wins on the bounce.
