Barcelona have secured Sergi Rosanas to a new contract.
The 19 year-old fullback has penned new terms to 2023, with the deal including an improved €50m buyout clause.
Rosanas played with Juvenil A last season, but is expected to be promoted to Barca B for next term.
A pacy fullback 'in the style of Barca', Rosanas saw action in this season's UEFA Youth League.
The defender joined Barca 11 years ago from Vilassar de Mar.
