Arsene Wenger insists Barcelona should not be allowed to join the Premier League.
Barca president Josep Maria Bartomeu has admitted the club will consider playing outside of Spain if Catalonia gains independence.
And his comments were backed up by La Liga chief Javier Tebas over the weekend, who conceded he could see the league going forward without the Nou Camp giants.
It has led to suggestions that Barca could play in the Premier League but Wenger is not having in it.
The Arsenal boss believes it would make much more sense for Celtic or Rangers to enter the English game.
"I hope Barcelona continue playing in Spain. It would break the geographical unity and common sense," he told beIN Sports.
"Why don't they invite Celtic or Rangers to the Premier League who are already part of Great Britain, that would have more sense than inviting Barcelona.
"On the other hand if the politics between Spain and Catalonia don't go well it would signify support from England for Catalonia and that would not be welcomed internationally."
Last month, Football League clubs ruled out the chances of Celtic or Rangers entering a new structure.
All 72 clubs held talks on switching from three 24-team divisions to four leagues of 20 - allowing for Premier League B teams and potentially the Old Firm clubs.
