Barcelona need to maintain their focus till the end of games to ensure they stop dropping points in matches they should have won, coach Hansi Flick said on Saturday, after his team slipped to third in LaLiga due to a four-match winless streak.

The 25-year-old joined Barcelona in 2018 from Uruguayan side Boston River and has established himself as a core member of Hansi Flick's team.

Barcelona were 4-2 down towards the end of the match before goals from Robert Lewandowski, Eric Garcia and Raphinha secured their comeback.

The Catalan giants have won just one of their last eight league games, falling behind rivals Real Madrid and Atletico Madrid, but by contrast are flying high in Europe.

Record 31-time Copa del Rey winners Barcelona will face Valencia in the quarter-finals, after they were paired in Monday's draw.

Barcelona's last visit to face Benfica ended in a heavy thumping on the way to Champions League group stage elimination in 2021, but with young starlet Lamine Yamal propelling a team on the rise, hopes are far higher for the Catalans this time around.

Olmo has scored six goals and registered three assists in 18 appearances since joining Barca in the close season from RB Leipzig. The Catalans are second in the Champions League table, having won five of their six games.

The draw leaves the third-place Catalans five points behind leaders Atletico Madrid, who lost 1-0 at Leganes earlier in the day, but Hansi Flick's side could not take advantage.

 Barcelona put in a clinical display to lift their first trophy in more than a year, having no silverware to show for last season.

Kylian Mbappe put Madrid ahead but a dominant Barcelona hit five in response before their goalkeeper Wojciech Szczesny was sent off in the second half.

LaLiga leaders Real recovered from that setback and are on a five-match winning streak ahead of defending the Super Cup in Jeddah, Saudi Arabia, but coach Carlo Ancelotti is cautious.

Last season, around this time, there was a surprise package in Girona in the top three of LaLiga. However, a year later, the Spanish league has returned to the status quo, with Real Madrid, Barcelona, and Atletico Madrid -- the three giants of Spain -- occupying the top three spots on the table at the end of 2024.

Jude Bellingham and Rodrygo scored second-half goals to help Real to a 3-0 win over Mallorca after Barcelona beat Athletic Bilbao 2-0 in the other last-four clash.

Gavi put Barcelona ahead from close range after 17 minutes and teenage winger Yamal netted the second early after the break.

Barcelona signed Olmo in August for around 55 million euros ($57 million), but with the club unable to meet LaLiga's wage capthe attacking midfielder and Spain international was registered only for the first half of the season.

The future of Olmo and young forward Pau Victor at the Catalan giants has been on hold over a financial and administrative limbo that prevented their registration beyond 2024.

Manager Hansi Flick expressed frustration over Barcelona's struggle to acquire new players' licences for Dani Olmo and Pau Victor but remained optimistic ahead of their Copa del Rey match against Barbastro, praising the duo's attitude.

Barcelona's star winger Lamine Yamal has vowed to "come back better" after injuring his right ankle earlier this month during a La Liga match.

Barca have now gone three games without a LaLiga win having picked up five points out of a possible 21, suffering defeats by Leganes and Las Palmas in their previous two home games. They are three points behind Atletico having played a game more.

Pedri sent the Catalans ahead but second-half goals from Rodrigo De Paul and Alexander Sorloth helped Diego Simeone's side move three points clear at the top of the table, having played one match fewer than Barca.
