Chelsea manager Roberto di Matteo describes his team's performance during the 6-1 win over QPR as "very good" and says his players' "energy, drive and motivation" following the Champions League victory over Barcelona surprised him.

Di Matteo also adds that he is pleased for Fernando Torres, who scored a hat-trick against Mark Hughes' men, after what has been a difficult season for the Spain striker.
