Tottenham have vowed to ban fans guilty of offensive chanting during Sunday's derby victory over Arsenal.
Managers Harry Redknapp and Arsene Wenger both condemned abusive chanting from fans during Spurs' 2-1 win.
Former Gunners striker Emmanuel Adebayor, who now plays for Spurs, was taunted about the Togo national team being attacked before the Africa Cup of Nations in Angola in January 2010.
Redknapp and Wenger were also targeted for insults by sections of the crowd.
Tottenham said several fans from both the home and away sections of the crowd were ejected from White Hart Lane during the game.
"It is club policy to ban fans who are found guilty of abusive chanting," a Tottenham spokeswoman said.
In a joint statement, the clubs said: "[We] were extremely disappointed to hear the chants from supporters. Neither club tolerates foul language, racist chanting, homophobic chanting or any anti-social behaviour from its supporters.
"We shall be working closely with each other to identify the individuals involved."
Both managers had condemned the chants after the match.
"What was chanted at Emmanuel was disgusting," said Redknapp.
"There was some pretty disgusting chanting at me as well but that's life. How do you chant something like that at someone? You can't be right mentally. You need help."
The abusive songs also included those by Arsenal fans chanting about the recent Tottenham riots.
Redknapp added: "It's got no place anywhere in life. Emmanuel never said anything to me. I think he regretted what happened when he ran to the Arsenal fans after scoring for Manchester City the other season.
"Even then what did he really do? They are all shouting abuse and he ran up and said 'have a bit of that'. He's run up and slid on his knees and said 'I've scored'. It might have been a bit over the top but he'd been getting grief for 80 minutes and that's how he reacted."
Wenger, when asked if he was disappointed at chanting from both sections of support, said: "Yes. We respect everybody and want to be respected as well."
The Arsenal boss also brushed off a confrontation with Spurs coach Clive Allen at the final whistle, which appeared to centre on Wenger's apparent refusal to shake his hand.
Wenger said: "Nothing happened. I shook the hands of the Spurs manager Harry Redknapp and his assistant. How many people do I have to shake hands with? There were no words exchanged. "
