Harry Kane said the racist abuse that Tottenham team-mate Richarlison faced this week was "unacceptable" as he called on FIFA to ensure "the right consequences" happen.
The Brazil forward had a banana thrown at him while celebrating a goal with team-mates during the Selecao's 5-1 friendly win over Tunisia in Paris on Tuesday.
Richarlison used social media afterwards to appeal for strong punishment, while others including former England defender Rio Ferdinand have come out in support.
Now Kane has added his voice to pleas for the world governing body to get tough on racism, and backed his club-mate.
"It was very disappointing to see," Kane told ESPN Brasil. "I haven't seen [Richarlison] and had a chance to talk about the racism that he suffered against Tunisia.
"I think FIFA have said they are going to investigate and find out what happened, but normally, that kind of thing is unacceptable."
Kane, captain of England, added: "I think we're doing all as much as we can do as players to kick out [racism] as much as possible. I hope FIFA can be strong and find out who done it, making sure the right consequences are made."
Kane further vouched for Richarlison's personal attributes, saying: "He's a great guy. He works really hard and is really professional. I'm really happy to have him in our team."
