Racial abuse overshadows Chelsea's London Derby win over Tottenham

FIFA's protocol for dealing with discrimination at soccer games was implemented for the first time in the Premier League on Sunday with three stadium announcements during a London derby between Tottenham and Chelsea, following apparent racist abuse toward Chelsea's Antonio Rudiger.

Rudiger, who is black, was seen putting his hands under his armpits - seemingly mimicking a monkey gesture - in the 63rd minute.

The third announcement came in injury time, by which stage - according to FIFA protocol - the game should have been abandoned.

Chelsea captain Cesar Azpilicueta said Rudiger had told him he heard "monkey noises" toward him in the crowd, and therefore reported it to referee Anthony Taylor.

Racial abuse overshadows win

"We are very concerned and aware of this behaviour," Azpilicueta said.

"All together, we need to make it stop. I hope everything gets clear and we eradicate it as soon as possible. It's an issue not just in football but in life."

According to FIFA protocol, the second step of the protocol should be an announcement leading to the suspension of the match and the players returning to the locker room for a specific period. If the discrimination continues, the third step should the abandonment of the match.

It was not immediately clear if there had been repeated incidents of racism, or if the announcements were referring to the first incident reported by Rudiger.

"I saw the referee follow the protocol," Tottenham manager Jose Mourinho said. "He came to Andre Marriner [the fourth official], he came to me and [Chelsea manager] Frank Lampard and told us what was happening."

The racist abuse overshadowed an accomplished performance by Chelsea in a 2-0 win that cemented its fourth place in the Premier League.

Lampard gets one over Mourinho

Earlier, Manchester United lost 2-0 at last-place Watford, with a goalkeeping howler by David De Gea - for the second weekend running - leading to the first goal at Vicarage Road.

Chelsea is four points clear of fifth-place Sheffield United, while the gap is six points to Tottenham in seventh place and seven points to United in eighth with nearly half the season gone.

Chelsea's win saw Lampard get one over Mourinho, his one-time coach and mentor at Stamford Bridge, in their first managerial head-to-head in the Premier League.

Mourinho will point to a pair of rash moments by his players, first goalkeeper Paolo Gazzaniga and then Son.

Tottenham was already trailing 1-0 to a goal from Willian following a quickly taken corner, when Gazzaniga came flying out of his goal and pole-axed Marcos Alonso with a studs-first, chest-high lunge to concede a penalty in first-half injury time. Referee Taylor originally awarded a free kick against Alonso, somewhat bizarrely, only to reverse the decision after an invention by the video assistant referee.

Willian converted the penalty for his second goal of the game.

Son's red card came after he was tackled by Rudiger near the touchline. Son was unhappy at the challenge and, while on his back, flicked his right foot into the chest of Rudiger, who fell backward to the ground.

"Does Rudiger have broken ribs going to the hospital?" Mourinho said. "Other people call it intelligent by Rudiger."

Racism toward Spurs' forward

A Chelsea fan was arrested during Sunday's Premier League game at Tottenham for allegedly racially abusing Son Heung-min.

There was no immediate indication when any racism toward Son happened.

"Chelsea Football Club will not tolerate any form of racism, nor is there a place at this club for anyone who is found to have engaged in such behaviour," Chelsea said in a statement. "If a season ticket holder or member is involved, we will take the strongest possible action against them including bans. We will also support any potential criminal proceedings by the relevant authorities."

Tottenham said Monday that its investigation into the racism aimed at Rudiger had been "inconclusive" as it worked to look into the abuse of Son.

"The club strongly condemns any such behaviour against any player and we will assist Chelsea and the relevant authorities in any way we can," Tottenham said.
