The 17-year-old Barcelona defender faced his toughest challenge yet when he went up against a dominant Paris Saint-Germain attack led by Kylian Mbappe. Cubarsi made his LaLiga debut in January, just two days before turning 17.
This match marked only his 15th appearance with the first team and his second in the Champions League.
He was on track to become the youngest player to feature in a Champions League quarter-final if not for his 16-year-old teammate Lamine Yamal also starting the game.
Despite the pressure, the defender delivered an impressive performance. In the first half, he led the pitch in clearances and finished the opening 45 minutes with a remarkable 92.59% passing accuracy.
Barcelona has seen great performances from La Masia graduates this season, with Yamal, Fermin Lopez, and Marc Guiu making significant impacts. Gavi and Pedri have also been standout players. Cubarsi should be included in the list of promising talents from the academy.
