Tottenham Hotspur have revealed that stewards will wear headcams in order to monitor fans' behaviour when Chelsea travel to White Hart Lane on Thursday evening.

There are fears that Chelsea skipper John Terry will be targeted after he was charged with using racist language against QPR's Anton Ferdinand.

A club source stated: "The club will take action against anyone heard using such language. Stewards will again wear headcams ... and will adopt a zero-tolerance policy.

"We do not tolerate discrimination of any sort at the club, on the pitch or in the stands."

Tottenham will strengthen their grip on third spot in the Premier League if they can overcome Chelsea on Thursday.
