Tottenham midfielder Rodrigo Bentancur has apologised to captain Son Heung-min for using a racial slur on Uruguayan television, saying it was a "very bad joke".
While appearing on Canal 10 show Por La Camiseta, Bentancur was asked by host Rafa Cotelo for a Spurs player's shirt.
The Uruguay international replied: "Sonny's? It could be Sonny's cousin too as they all look the same."
After backlash to the clip, which was circulated on social media, he apologised to the South Korea international on Instagram.
"Sonny brother," he wrote. "I apologise to you for what happened, it was just a very bad joke.
