Chelsea manager, Thomas Tuchel, has admitted N’Golo Kante is an injury doubt for their Premier League opener against Crystal Palace on Saturday.
Kante was taken off midway through the second half of the Super Cup victory over Villarreal on Wednesday.
The France midfielder is now unlikely to feature at Stamford Bridge.
“There is an issue with N’Golo Kante from the [Super Cup] final we need to sort.
“The decisions are not made yet, who starts and who we push over the line,” Tuchel told the media on Friday.
Tuchel also said Hakim Ziyech, who scored Chelsea’s only goal on Wednesday, had suffered a serious shoulder injury.
But the Moroccan could return to training within a fortnight.
“Hakim is out for sure. It will be treated conservatively, we don’t need surgery which is good news,” he added.
