Tottenham summer signing Heung-Min Son has promised manager Mauricio Pochettino he "will come back stronger" from international duty ahead of being fully fit for the two upcoming derbies against West Ham on 22 November and Chelsea one week later – with a Europa League game against Qarabag inbetween.

The Argentinian manager recently expressed his concerns on the South Korean going with his national team after he just returned to action following more than five weeks on the side-lines due to a foot injury. Son made just two substitute appearances in the Europa League win over Anderlecht and the weekend's draw at Arsenal. "We need to speak a little bit to arrive at the best thing for him, for his national team and for us. It is a very long way [to go]. It is another matter and we need to speak with him and with the national team," the manager said.

But Son has now claimed that he is fit and looking forward to replicating his impressive start to the season in the coming derbies, as the 23-year-old scored three goals in five appearances before the injury.

"I am fit and getting better and stronger," he said to the club website. "I always think I can play better. I will come back stronger. I'm excited for the next derbies as well, they are important for us and our fans. We have to be very fit for these games.

"It was crazy and unbelievable for me to sit on the bench [against Arsenal] and take in the atmosphere. It was very exciting. The game had a great atmosphere and we were unlucky to only draw 1-1. We played very well and had chances to win but that is football and we have to learn from it. We played well and had more chances than them. We attacked well, especially in the second half. Harry, Christian and Toby had big chances. I want to win every game, so it's two points dropped."

Meanwhile, South Korea manager Uli Stielike has also played down Pochettino's concerns after claiming that they are also closely monitoring the condition of the star ahead of the World Cup qualifier against Myanmar.

"If Son Heung-min wasn't 100% recovered, his club team would have said something to us," he said as quoted by The Mirror. "Both the national team and his club team are monitoring his condition. I wouldn't have picked Son Heung-min if I didn't think he couldn't play against Myanmar."
