Tottenham say they are investigating after Chelsea defender Antonio Rudiger was allegedly targeted with racist abuse in Spurs’ 2-0 defeat on Sunday.

After an incident in the second half, three separate announcements were made inside the stadium informing supporters that racism was "interfering with the game."

Referee Anthony Taylor stopped play and spoke to the players and managers before the game resumed.

In a statement, Tottenham said: "We are now conducting a thorough investigation which will include liaising with Chelsea and their players for their observations.

"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."

Chelsea manager Frank Lampard said that Rudiger had heard racist chanting coming from the stands during the game.

Speaking after the game, Lampard said: "All I know is that Toni Rudiger said that he heard racist chanting and comments.

"I haven't had an individual conversation with Toni, I've only addressed the group.

"Of course I'll support Toni, as we would support any of our players, in fact an opposition players whenever this happens, whatever stadium it happens at, it needs to be dealt with.

"We're much more aware of the fact that we have a protocol to report it which is a positive step.

"Of course you wish that it's not needed. If it's fact and true that it happened then it needs to be dealt with and punishment needs to be strong."

Spurs manager Jose Mourinho also condemned the reported abuse after the game.

He said: "I hate racism in society, I hate racism in football and I'm disappointed that things like that still happen.

"The ref stopped to the game, spoke to the players and the captains, the coaches.

"In that moment I think everyone is together because racism is a sad thing in society and a sad thing in football."
