Barcelona are pushing to secure Sergi Roberto to a new deal amid fresh interest from Manchester City.
El Mundo Deportivo says the Spanish giants are desperate to keep him out of Pep Guardiola's clutches in January.
City are preparing to meet Roberto's £35million release clause this winter.
But fresh reports allege that Barcelona will attempt to raise that figure to an astonishing £350m.
Roberto is considering his options after struggling to secure a regular start in coach Ernesto Valverde's plans.
