Due to the well-known shortage of personnel in the Tottenham team and the impact of the suspension caused by the epidemic, Spurs have played five high-intensity games in the past 11 days, and Son Xingyu has played all the matches. After the games against Southampton and Watford, Son Xingyu was exhausted, and after the game against the Hornets, Son Xingyu was so tired that he fell to his knees directly on the ground. In the second half of the League Cup and Chelsea, Conte replaced Son Heung-min early, and after the post-match examination confirmed that Son Heung-min's hamstring injury, Conte confirmed that Son Heung-min may not return until February 9 against Southampton.
"As you can see, it was a bit strange against Chelsea, when I replaced Son Heung-min and Lucas Jr. together. But it wasn't because of injuries, it was because I wanted to give them a little rest. However, the next day Sun Xingyu felt uncomfortable in his legs, and after a scan, we are still waiting for the most accurate judgment of the medical department. But it's clear that Son is injured and I don't know when he'll be able to come back, maybe only to resume training during the national team matchday. Conte said.
Conte judged that Son would not return until the Premier League match against Southampton on 9 February, during which he would miss many key matches for Tottenham. In addition to the second leg of the League Cup against Chelsea at home, there are also league games against Arsenal, Leicester City and again against Chelsea.
Now Conte is also very worried that kane, who is just as tired, will also be at risk of injury, after all, Kane has suffered six major leg injuries in the past three seasons. "Honestly, Kane played 6 games in 17 days and if possible, I'd like to give Kane a break. But not letting Kane start was a difficult decision. But if I try to take risks in some races, I also feel right. Conte said.
Currently in tottenham's forward line, there is only one center for Kane, without any substitutions. The position of Son Heung-min's injury stop will be replaced by Hill or Berwyn, who is close to returning from injury, but these two players cannot play the role of Son Heung-min.
