Blues lose out in Rome
Ten-man Chelsea suffered a surprise 3-1 defeat to Serie A strugglers Roma in Champions League Group A.
Christian Panucci put the home side in front after 34 minutes and Mirko Vucinic scored twice in 10 second-half minutes to put the result beyond doubt.
John Terry pulled a goal back after 75 minutes but Deco was then sent off for a second bookable offence to complete a miserable night for the Premier League leaders.
