West Ham vowed to track down and ban any more of their supporters who were at fault during Sunday's match.

"West Ham United are in contact with Tottenham Hotspur to assist them with their investigation into the conduct of a small number of supporters and alleged inappropriate chanting during yesterday's match at White Hart Lane," a statement read.

"The majority of West Ham supporters went there and supported their team in the proper fashion. They were let down by a tiny minority.

"West Ham United will take the strongest possible action against any of their supporters, including enforcing life bans from the club, that are found guilty of behavior which is categorically not condoned by West Ham United."
