Barcelona have apologised for mocking Real Betis following a 5-2 win over their La Liga rivals on Sunday.
Following the home victory, Barcelona tweeted a photo of former Real Betis defender Junior Firpo holding up five fingers with the caption 'Junior knows'.
The club tweeted: "Barcelona wish to sincerely apologise for any offence caused to Real Betis."
"No disrespect was intended, but we were wrong to publish it on a night that was very special for Junior."
