Marc Guiu Paz (; born 4 January 2006) is a Spanish professional footballer who plays as a striker for Barcelona Atlètic.
Club career
Born in Granollers, Barcelona, Catalonia, Guiu began his career with Penya Barcelonista Sant Celoni, a fan club of La Liga side Barcelona. He went on to join Barcelona themselves in the 2013–14 season, and progressed through the La Masia academy, and was called up to the senior squad for the first time in June 2023, ahead of pre-season matches against Celta de Vigo and Japanese opposition Vissel Kobe. Guiu made his unofficial debut for Barcelona in the latter game, coming on as a half-time substitute for Robert Lewandowski.
On 11 October 2023, he was again called up to the senior squad for a La Liga fixture against Granada, though he did not eventually feature in the game. In the same month, he was named by English newspaper The Guardian as one of the best players born in 2006 worldwide. On 22 October, Guiu made his senior competitive debut as a 79th-minute substitute, scoring the winning goal in 23 seconds with his second touch of a 1–0 victory over Athletic Bilbao. At 17 years and 291 days of age, he became the youngest and fastest debutant to score for Barcelona in La Liga.
International career
Guiu has represented Spain at youth level.
Style of play
Barcelona youth coach Iván Carrasco describes Guiu as a "classic '9', a specialist in the area who exploits his physical power". He has a good high ball game, pace, strength and work-rate. Spanish football expert Guillem Balague described Guiu as a striker who is known to be "more efficient in the box".
