Emirates and White Hart Lane rivals join forces to root out culprits.
Arsenal and Tottenham Hotspur will join forces to name and shame supporters who made abusive chants during the north London derby on Sunday.
Both clubs condemned the signing from fans who have a history of hating each other – a rivalry that has grown ever more intense over the last few years.
Spurs fans sang vile songs directed at the Gunners boss Arsene Wenger, while they also booed defender Bacary Sagna while he was being stretchered off with a broken ankle.
Arsenal fans were no better, chanting songs about Wenger’s counterpart Harry Redknapp and taunting Emmanuel Adebayor about the shooting of the Togo bus in Angola.
The clubs say they will be “working closely with each other to identify the individuals involved.”
The joint statement says “neither club tolerates foul language, racist chanting, homophobic chanting or any anti-social behavior from its supporters.”
Tottenham revealed several fans were ejected from both sections of support and they will make sure anyone found guilty will be banned for life.
“It is club policy to ban fans that are found guilty of abusive chanting,” a club spokeswoman said.
“We evicted several fans at the time during the match. The way we deal with large numbers is we take out one or two of the ring-leaders who are initiating the chants.”
