FC Barcelona took a crucial step toward the UEFA Champions League quarterfinals by securing a 0-1 victory over Benfica in the first leg of the Round of 16 in Lisbon. However, the tie remains open, and Hansi Flick's side must finish the job in the return leg on March 12 at the Estadi Olímpic Lluís Companys.

What Results Would Qualify Barcelona?

With the first-leg advantage, Barça has multiple ways to secure its spot in the next round:

Win the second leg: Any victory at home guarantees qualification.

Draw: A draw in regular time is enough to advance.

Lose by one goal and win on penalties: If Benfica wins 0-1, the match will go to extra time, as the away goals rule no longer applies. If the score remains tied after 120 minutes, the winner will be decided in a penalty shootout.

However, Barcelona will be eliminated if they lose by two or more goals.

Key Factors for the Second Leg

Defensive Solidity: Barça displayed great resilience in Lisbon, even after going down to 10 men in the 22nd minute following Pau Cubarsí's red card. Keeping a solid defensive structure at home will be crucial.

Raphinha’s Form: The Brazilian winger continues to be one of the team's most decisive players, and his influence in attack will be key in preventing Benfica from gaining control of the game.

Home Advantage: A packed Estadi Olímpic Lluís Companys could provide the extra push needed to secure qualification.

With a slender but vital advantage, Hansi Flick’s side has a great opportunity to seal a spot in the quarterfinals and keep their Champions League dream alive.
