He played a key role in Spurs’ resurgence under Antonio Conte and their qualification for the Champions League.

Despite all that, Son Woong-jung is demanding more and wants him to be at least ’10 per cent better’ at all times.

This season, the attacker for Tottenham Hotspur scored 23 goals in the Premier League and shared the Golden Boot with Mohamed Salah, the star player for Liverpool.

He was a major factor in Spurs’ Champions League qualification and their comeback under Antonio Conte.

Son Woong-jung, however, is still expecting more from him, stating that he should always be at least “10 percent better.”

He must be able to play a solid role in one of the world’s top clubs,” he continued. “That’s when he will become a world class player.

“He scored a lot of goals this year, but it doesn’t mean he will do the same next year.

“Only those who stay ready can survive the difficulties. He must face everything with a cautious mind and can’t afford to be too proud.”

Son was on 21 goals heading into the final day and scored a brace in Spurs’ 5–0 win over Norwich City.

Salah was on 22 and scored against Wolverhampton Wanderers, which saw Son humorously ask for updates on his rival mid-game.

Post-match he told reporters: “It’s incredible to have this award. I can’t believe it. I got really emotional. I dreamed of it as a child. Literally it’s my in hands. I can’t believe it.”
