Tottenham assistant boss Cristian Stellini has praised attacker Heung-min Son.
The South Korean was benched for their 2-0 win over West Ham United on Sunday.
However, Son came off the bench to score the second goal in the Premier League win.
Post-game, Stellini told reporters: We know that Sonny's response would be perfect because Sonny is a perfect guy. But after the World Cup, sometimes it happen that the player are not fit 100 per cent. In that moment you have to take a decision and it is difficult with a player like Sonny to drop them, but you have to do it because we have a lot of matches.
The risk is you lose a player for a long time and we don't want to do it. We want to use Sonny in the right way. Now we had Richarlison back 100 per cent fit and we pick the team to play this type of game. The plan was clear. We had to fight in the first half and when they stretch the team and we have more space, we can use players like Sonny and players to attack the space."
He added: No, the confidence is 100 per cent, it is physically that he need to recover. When he play five games in a row, sometimes you can feel tired and you can feel something not perfect. It is important for us that the player is mature enough to say this.
It is important because you can't manage the performance of 11 player. If you have 11 100 per cent, it is better to have seven and three that are not performing well but you need that they are mature and they speak with us. Sonny in this case was perfect during the week but now we have time to manage him to play the next step with six games in 14 days."
