Tottenham need Heung-min Son at his best if they are to have a great season.

That is according to boss Antonio Conte, who knows that his South Korean star is so important to his team's style of play.

Son has only five goals for Spurs this term, which came in two matches, which means he has not scored in 19 games.

As Spurs prepare to take on Crystal Palace on Wednesday, Conte said, "Son for sure is trying to find the best form. After the injury he had against Marseille he struggled a bit and also in the World Cup he didn't score.

"But we are talking about a player that if we put him in this discussion we are in trouble, because Sonny and Kane are the two most important players with Hugo Lloris.

"If we start to put into discussion them or to have doubts about them, then I think we are really in trouble.

"For sure a team like us we need in every game, injuries or not injuries, the most important players to give their best, but you know across a season in 60 games that you can't play every game at the peak of your form and make a difference. This is normal.

"But for sure we are talking about three players in Sonny, Kane and Hugo, who can make the difference. Our expectations are always very high for them. I think their commitment, their will, their desire is always the same. They know the role they have in the squad."
