John Terry expects to play for Chelsea against Levski Sofia on Wednesday night after recovering from the back problem which kept him out of Saturday's win at Fulham.
Khalid Boulahrouz is also back from an eye infection and Joe Cole is the only Chelsea player missing for the Champions League Group A clash in Bulgaria.

Provisional squad: Cech, Ferreira, Boulahrouz, Carvalho, Terry, A Cole, Bridge, Geremi, Makelele, Essien, Diarra, Lampard, Ballack, Mikel, Robben, Kalou, Wright-Phillips, Drogba, Shevchenko, Cudicini.
