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. Guiu made his Champions League debut three days later in a 2–1 win against Shakhtar Donetsk. He scored his first goal in the competition and second of the season on 13 December in a 3–2 defeat against Royal Antwerp.

He has a good high ball game, pace, strength and work-rate. Spanish football expert Guillem Balagué described Guiu as a striker who is known to be "more efficient in the box".
