Barcelona open their 2026-27 Champions League campaign Wednesday against Feyenoord at the Olympic Stadium, beginning another attempt to reclaim the European crown they last won more than a decade ago.

Hansi Flick's side have made a perfect start to the domestic season, winning their first four La Liga matches against Elche, Athletic Bilbao, Rayo Vallecano and Valencia while scoring 17 goals.

They enter the Champions League opener at the top of the Spanish league and with confidence building around a team that has made no secret of its ambitions in Europe.

Barcelona's fifth and most recent European Cup triumph came in 2015, when they beat Juventus in the final. Their wait for another title has since grown longer, with the Catalan club suffering a quarterfinal exit to Atletico Madrid last season after reaching the semifinals the year before.

The defensive problems that contributed to their 2024-25 semifinal elimination remain one of the biggest questions surrounding Barcelona. Their attacking quality, however, is difficult to overlook, and Flick has several players competing for starting places as he looks to give his team the strongest possible start to their European campaign.
