Fernando Torres returns to the starting line-up and makes his 100th Chelsea appearance, with Demba Ba on the bench.
Oscar comes into midfield with Victor Moses away on international duty. The rest of the midfield and the defence are unchanged so Ramires will again play alongside David Luiz in the deeper midfield roles.
For Swansea, Gerhard Tremmel replaces Michel Vorn in goal, as he has done throughout their Capital One Cup campaign. Michu returns up front with Danny Graham making way. Pablo Hernandez, captain Ashley Williams and Angel Rangel also come back in.
