Roberto Di Matteo admitted Chelsea must avenge their Champions League defeat at Shakhtar Donetsk in two weeks time if they are to avoid one of the shortest defences of the trophy.

The European champions crashed to a 2-1 defeat to Shakhtar as John Terry's return to the side went awry at the Donbass Arena to leave them facing a real fight to qualify for the knockout stage.

Previous holders have never failed to do so and Di Matteo acknowledged Chelsea now had to win their home games against Shakhtar and Nordsjaelland to maintain that record. The Blues boss said: "We need to win our two home games remaining for sure."
