The striker spent last season on-loan with Alaves.
Sport says Barcelona's initial idea was to keep Paco Alcacer in the squad and let Munir go, as long as Alcacer didn't get a huge bid.
That proposal may come in the coming weeks so he would leave and they would not put obstacles in his way to go, provided they get the 30m euros they paid for him.
Alcacer's exit would not be covered by a top level signing as it is considered the squad has sufficient offensive solutions. And that's where Munir comes in, a player who impressed on loan. Valverde wants him as an alternative in attack.
