Tottenham Hotspur have released a statement after their Premier League match with Chelsea saw three announcements over the public address system regarding racist abuse from the stands.
Antonio Rudiger claimed he had been targeted by some supporters during the game, and told his captain Cesar Azpilicueta and referee Anthony Taylor that monkey noises had been directed at him.
"We are now conducting a thorough investigation which will include liaising with Chelsea and their players for their observations," read the statement from Spurs.
"Any form of racism is completely unacceptable and will not be tolerated in our stadium.
"We take any such allegations extremely seriously and shall take the strongest possible action against any individual found to be behaving in such a way, including stadium bans."
Speaking after the match, Chelsea manager Frank Lampard commented on the incident.
"All I know is Rudiger said he heard a racist chant," he said. "But I don’t know any more. I will support him.
"I don’t know if it is getting better or worse. We have a protocol to report it. If it is fact then we need to deal with it.
"In terms of walking off the pitch, it has to be a feeling on the pitch."
Jose Mourinho also spoke about the incident in his post-match press conference.
"I'm in the game, I'm focused on the game, I'm too far from the area where it looked like the incident happened. I don't have much to say other than it's something that saddens me.
"I hate racism in society, I hate racism in football. I'm disappointed that things like that still can happen, but the referee stopped the game. He spoke to the players, he spoke to the captains, he spoke with the coaches.
"I was losing, I didn't want the game stopped but immediately when I knew the reason why it was stopped I obviously understood and accepted it.
"The club is also a very proud club in this kind of situation and the club also internally will try to delete it."
