Sept 13 (Reuters) - Chelsea midfielder N'Golo Kante will not be involved in the club's Champions League opener against Zenit St Petersburg, manager Thomas Tuchel said on Monday ahead of their Group H clash against the Russian side. Tuchel was hopeful Kante would be back in action against Zenit but now expects the 30-year-old to return for Sunday's Premier League trip to Tottenham Hotspur. "N'Golo had two training sessions yesterday and trained again today, but the Champions League game comes a bit too early for him" Tuchel told a news conference ahead of Tuesday's match at Stamford Bridge. Tuchel added Chelsea will also be without American forward Christian Pulisic as he continues to recover from an ankle injury. "It's been difficult for him, from a Champions League win, then it was individually for him a tough Euros because he felt he could have played a part for England," Tuchel said.
