Ansu Fati's release clause has automatically increased to €400 million ($466 million) after Barcelona officially promoted him to the first team.

Fati will inherit the No.22 shirt which was vacated this week by Arturo Vidal, who joined Inter Milan.

Fati became Barca's youngest ever scorer in La Liga when he scored a header against Osasuna aged 16 years and 304 days last August.
