European Club Association president Nasser al-Khelaifi has urged Barcelona to quit the Super League rebel group.
Juventus announced their decision to leave last week.
PSG supremo Al-Khelaifi said of Barca: "Of course we want them to come back, it'd be better for them.
"They will be in a better position if they are back. People will respect them more, try to help them more.
"At the moment, they are on their own. Right now it seems like they're against everybody, which is not good for them."
