In a moment that will forever define his young career, Álvaro Cortés made his long-awaited debut for Barcelona on Wednesday night against Alavés. Despite the team falling to a narrow 1-0 defeat, the emotional rollercoaster was undeniable—the 19-year-old described it as the "happiest day of my life."

Speaking after the match, Cortés opened up about the whirlwind of emotions. "It’s a bittersweet feeling. I have a lot of mixed emotions about the match. My debut is the happiest day of my life—with the club I've supported since I was a kid, and with my family and friends in the stands. Now all that’s left is to work hard so that more opportunities come."

The young defender also revealed the pre-game pep talk from manager Hansi Flick that helped calm his nerves. "I found out at lunch, when he asked me if I was ready. Flick told me to do what I do in training—to do what I know how to do. My teammates have given me positive messages, and that gives you a boost of confidence for the match."

Cortés credited the support of familiar faces like Pau Cubarsí and Gerard Martín for making the transition smoother. "I'm two years older than Pau, but his career is incredible. Everything he's achieved is admirable. Gerard and Ronald have also given me advice. Playing alongside these guys makes everything easier."

While the result stung—ending Barcelona's hopes of a 100-point season—Cortés remained focused on the bigger picture. "This match was crucial for them. It didn't go the way we wanted, but we congratulate Alavés on their victory and will continue working."

The Catalans now turn their attention to Sunday's home clash against Real Betis, where Cortés will hope to build on his emotional first step in blaugrana.
