Manchester City boss Pep Guardiola is fighting to keep hold of Gabriel Jesus.
Juventus are chasing a summer deal for the Brazil international.
But Guardiola doesn't want City chiefs to set an asking price for Jesus, who he believes has not yet reached his full potential, reports the Daily Express.
The Spaniard was instrumental in bringing Jesus to the Etihad and it was his phone call that convinced the Brazilian to sign for City.
Guardiola appreciates what Jesus does for the team and thinks he can become one of the top three strikers in the world over the next few years.
