Six Nations 2013: Gloucester duo reveal England hopes

Gloucester fly-half Freddie Burns and centre Billy Twelvetrees talk to BBC Points West about their ambitions for the forthcoming Six Nations, which starts next month.

The duo's performances at club level have earned them a call-up to Stuart Lancaster's 33-man England squad.

Burns made his international debut against New Zealand in the autumn series, while Twelvetrees is looking for his first cap.
