The north London club will pay an initial £50m for the former Watford man, plus an additional £10m in add-ons.
Richarlison joins the growing Brazilian squad at Tottenham, which also includes international teammates Lucas Moura and Emerson Royal.
Spurs players may have to watch their backs in training as Richarlison has built a reputation as a quick dealer on and off the field.
Back in 2020, when he was off international duty with Brazil, Richarlison managed to beat City goalkeeper Ederson during a training session with the national team.
While Ederson was trying to save his penalty kicks, Richarlison was mocking him from behind the goal.
“F*** Ederson!” said the former Everton striker.
“Shut your mouth, man,” Ederson replied.
Richarlison replied, “I cheer you on, you idiot! Then I’ll cheer you up. I hope you score.”
Richarlison then laughed at Ederson after he conceded a goal, prompting the City goalkeeper to volley in the direction of his teammate and Benfica winger David Neres.
It all looked fun and matches between Richarlison and Ederson, who later said in a 2021 interview that he would bring the striker to Manchester City if he had the chance.
Ederson said when asked which of his Brazil teammates would like to sign for City TNT Sports: “I’ll bring the pigeons (Richardison’s nickname) to chat.
“He’s an idiot, a clown. There are so many words I can put on him.”
Ederson isn’t the only Brazilian to end up at the hands of Richarlison while on international duty.
In June, Real Madrid star Vinicius Jr was forced to part ways with the Tottenham striker after the pair faced off during a training session.
Veteran players Dani Alves and Neymar had to intervene after the duo nearly collided before a friendly match against Japan.
However, it was later said that the incident was not as serious as it first appeared and that the two players were only joking.
While Richarlison’s new Tottenham teammates are likely to see the funny side of his training ground behaviour, it remains to be seen how stern Tottenham boss Antonio Conte will react.
