Richards’ comments come amid news that Chelsea goalkeeper Edouard Mendy is required to have a tooth operation, ruling him out of international duty with Senegal.
The 29-year-old missed the FA Cup quarter-final victory over Sheffield United on Sunday, and Tuchel confirmed that his no. 1 was booked in to see the dentist soon.
“Mendy will stay because he has an operation on his tooth,” said the German.
“He needs to see the dentist because it needs to be done. It’s why we do it now [so he can be back after the international break].”
