Tottenham boss Antonio Conte has declared Heung-min Son "world class".

The South Korea striker is back home for this week's preseason training.

"He knows my thoughts about him," said Conte. "Every time I had the pleasure to speak about him, I can tell only positive things.

"We are very lucky he stays with us and I am very lucky to have him in my team. It's a pleasure to have a player like him. Always with a smile and you can see during training, always a great attitude, great commitment.

"He is top class, with fantastic quality with right foot and left foot, and he runs a lot. It's very difficult to ask for more from your player. We are talking about a world-class player, one of the best in the world."
