Chelsea manager wants 'perfect game' to beat Shakhtar

Roberto Di Matteo says Chelsea will need to play a "perfect game" to beat group leaders Shakhtar Donetsk when the two sides meet on Wednesday.

The Chelsea manager confirms Ashley Cole has been ruled out of the game with a hamstring injury sustained against Swansea, with Ryan Bertrand set to deputise at left-back, but says the team will be boosted by the return of club captain John Terry following his domestic suspension.

The Ukrainian league leaders are three points ahead of the Champions League holders in Group E after winning 2-1 against the Blues when the two sides met a fortnight ago.
