Full-back Jose Bosingwa is out with a knee injury while the Blues will give a late fitness test to Frank Lampard, who picked up an ankle knock while on England duty in midweek.

Didier Drogba (groin), will also be fit to take on the Baggies after he had to settle for a place on the substitutes' bench in last week's Community Shield.

Provisional squad: Cech, Hilario, Turnbull, A Cole, Kalou, Drogba, Terry, Alex, Malouda, Lampard, Essien, Mikel, Benayoun, Anelka, Zhirkov, Kakuta, Sturridge, Ferreira, Bruma, Ivanovic.
