Demba Ba has been preferred to lead the Chelsea attack ahead of Fernando Torres for this evening's League Cup semi-final second leg against Swansea City.

The Senegalese frontman will be supported by Juan Mata and Eden Hazard, both of whom have been given wide roles at the Liberty Stadium.

Like Chelsea, hosting Swansea will also play with one striker in the form of Spaniard Michu.

Meanwhile, Gerhard Tremmel will start in goal instead of Michel Vorm.

Swansea: Tremmel; Rangel, Williams, Chico, Davies; Britton, De Guzman, Ki; Routledge, Hernandez; Michu

Chelsea: Cech; Ivanovic, Cahill, Azpilicueta, Cole; Ramires, Lampard, Mata, Oscar, Hazard; Ba
