N’Golo Kante is set to miss the Europa League semi-final second leg match at Stamford Bridge on Thursday and faces two weeks on the sidelines with a hamstring problem, Sarri said during a pre-match conference on Wednesday.
France midfielder Kante left the field with just 10 minutes into Chelsea’s 3-0 win against Watford and Sarri said it was his mistake to start him on that day.
The Blues will be hoping the 28-year-old World Cup winner will be ready for the final, should they reach the final in Baku on May 29.
“He had a problem with his hamstring, not very serious but he needs to rest for a couple of weeks,” Sarri said.
“We can try to recover him for only the final if we get there. I’m not sure if he can, but we can try.”
Ruben Loftus-Cheek, who is likely to fill Kante’s position, said the Blues will not slow down despite sealing a Champions League spot after leapfrogging Tottenham to third in the Premier League.
“We won’t be relaxed tomorrow, we have the Champions League qualification but we have the chance to win a trophy and that will be stupid to go into the match in a relaxed manner,” Loftus-Cheek said.
Sarri reiterated the remarks of the 23-year-old but warned his side of the danger posed by Frankfurt.
“I think we have reached the target of the club, so we’re very happy. We have to play in another competition. We have to reach the final and try to win,” Sarri added.
“It’s not easy because we have to play a dangerous team as we saw in the first leg. They’re dynamic and aggressive and when they can find spaces, it’s a dangerous match.
“You have to play a semi-final against a strong team and it’s difficult to be favourite. I’m sure tomorrow they can play at their best… we need to be careful.”
