Chelsea have taken up options to sign striker Olivier Giroud and defender Thiago Silva on new one-year deals.
Frenchman Giroud, 34, and Brazilian Silva, 36, were due to be out of contract this summer but have agreed extensions for next season.
Earlier on Friday, Chelsea confirmed that manager Thomas Tuchel has signed a contract extension until 2024.
However, Argentine goalkeeper Willy Caballero, 39, will leave after four years with the club.
All three players were in the Chelsea squad for last Saturday's Champions League final, although Silva was the only one who featured in the win over Manchester City.
