Chelsea strikers Demba Ba and Fernando Torres are available for tomorrow's Premier League clash with Southampton following their struggle with a hamstring injury and illness respectively.

John Terry's comeback from a knee problem will continue, although he is short of match fitness and is unlikely to start at Stamford Bridge.

Nigeria duo John Obi Mikel and Victor Moses are unavailable as they are at the African Nations Cup.

Provisional squad: Cech, Turnbull, Azpilicueta, Ferreira, Ivanovic, Luiz, Cahill, Terry, Cole, Bertrand, Lampard, Ramires, Mata, Oscar, Hazard, Marin, Torres, Ba, Ake.
