Ronald Koeman has confirmed that goalkeeper Neto has asked to leave the club in the January transfer window.
The 31-year-old joined Barcelona from Valencia in 2019 and has made just 14 appearances since, featuring nine times this season.
Reports emerged this week claiming the one-time Brazil international wants to depart Camp Nou and he has been linked with a move to Arsenal.

Barca have turned down the shot stopper's request to leave, however, claiming he is too important to let go.
Koeman told reporters on Saturday: "It's true that his representative has asked the club for an exit and we have said no because he is an important goalkeeper for us and we want to be very well covered at each position.
