One of those is in midfield where Mateo Kovacic comes in for N'Golo Kante who is missing today with an ankle injury and another is up front.
Tammy Abraham returns with Olivier Giroud moving to the bench. Michy Bathshuayi, who scored twice in a PL2 game on Monday, is also among the subs.
Pedro was originally named in the 11 but Ross Barkley began the match instead.
In defence Kurt Zouma makes his 50th Premier League appearance for Chelsea.
