Spanish substitute striker Nacho Novo fired home the opening goal with a 20-metre shot after taking a neat pass from Chris Burke in the 86th minute.
Three minutes later Slovakian striker Filip Sebo cracked home another goal from 20 metres out which appeared to be flying wide until it took a deflection off a defender and went into the net.
The match was played in a competitive spirit with several tough tackles flying in from the two sides who finished runners-up in their respective Scottish Premier and English Premier leagues last season.
Chelsea's best chance came with a first half header from Didier Drogba which flashed across the face of the goal.
