Di Matteo aims for 'impossible'

Chelsea manager Roberto Di Matteo says his side are aiming "to do the impossible" as they bid to become the first team to defend the Champions League title.

The 2011-12 winners open their campaign with a home tie against Serie A champions Juventus, with Di Matteo insisting there are no easy fixtures in Group E.

The 42-year old former Chelsea midfielder describes opponents Juventus as "one of the most difficult teams" in the Champions League.
