Return game with Shakhtar Donetsk is must win - Roberto Di Matteo

Chelsea manager Roberto Di Matteo says the Champions League is "very competitive" this year and they must now win at home against Shakhtar Donetsk.

The Champions League title-holders lost 2-1 on Tuesday night, after goals from Brazilians Alex Teixeira and Fernandinho put the Ukrainian club ahead.

Oscar thumped in a late consolation for Chelsea, but the defeat leaves the Blues below leaders Shakhtar Donetsk in group E.
