The 18-year-old missed the second half of last season after tearing the meniscus in his left knee in November 2020.
Fati sustained the injury during Barcelona’s 5-2 victory over Real Betis at Camp Nou, and has subsequently undergone three operations.
However, the Spain international is closing in on a return to action after he was photographed back on the training pitches at Barcelona's Ciutat Esportiva Joan Gamper training ground on Tuesday.
Although he will not be available for this weekend’s LaLiga showdown with Getafe, Fati could be in contention for Barcelona's trip to Sevilla on September 11.
The forward 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, who 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.
