Swansea City fullback Martin Olsson has revealed how Tottenham star Heung-min Son sought to wind him up when they clashed last week.

Olsson's Sweden and Son's South Korea will be facing off in the World Cup this summer.

On Son, Olsson told the Expressen: "He said that we'll see you this summer, it was a joke and so a cool thing.

"We both laughed about it. We'll keep it going."

On Swans teammate Ki Sung-Yueng, Olsson added: "Ki started right away. He's always carrying on about it."
