Ansu Fati is back in the Barcelona squad after spending 10 months out of action due to a knee injury.
The 18-year-old has been included in Ronald Koeman's 20-man group for the LaLiga game at home to Levante on Sunday.
Fati has not played for the Catalans in 322 days, having torn the meniscus in his left knee during a 5-2 win over Real Betis last November.
The winger, who underwent three operations, only returned to training in August.
Sunday's game at Camp Nou will offer Fati the chance to make his first competitive appearance since inheriting the number 10 shirt from Lionel Messi, who left the club at the end of his contract before signing for Paris Saint-Germain ahead of this season.
Fati has scored two goals in his two matches against Levante in LaLiga, only netting more against Villarreal (three) in the competition.
He became the youngest goalscorer in Barca's history when he scored against Osasuna in August 2019 aged 16 years and 304 days.
Fati has since added a further 12 goals in 42 appearances across all competitions for the Blaugrana, whom he joined at the age of 10.
The Guinea-Bissau-born youngster has been capped four times by Spain and scored his first international goal against Ukraine in September 2020.
Barca's 0-0 draw with Cadiz on Thursday piled further pressure on head coach Ronald Koeman, with president Joan Laporta reportedly keen to appoint Belgium boss Roberto Martinez in his place.
The Catalans have won two and drawn three of their opening five league matches of 2021-22 and are already seven points behind leaders Real Madrid, albeit with a game in hand.
