Tottenham and Arsenal have come together to work to find those responsible for the ugly chants during Sunday's bitter derby.

Sections of the home crowd taunted Arsenal manager Arsene Wenger, while some away supporters were widely condemned for mocking the deadly gun attack on the Togo team bus in January 2010 which Emmanuel Adebayor survived.

A joint statement read: "Both clubs were extremely disappointed to hear the chants from supporters at Sunday's game.

"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."
