Fernando Torres rediscovered his goal-scoring touch too late for Chelsea's Champions League hopes, with the English side becoming the first holders to exit at the group stage despite a 6-1 thrashing of FC Nordsjaelland.
On a bittersweet night for Chelsea, Torres ended a month-long goal drought by scoring twice in a match for the first time this season.
Chelsea went ahead in a frenzied spell in which both sides miss penalties before David Luiz scored from the spot in the 39th minute. Torres netted in first-half stoppage time.
Although Joshua John pulled one back for Nordsjaelland 20 seconds after the break, Gary Cahill began Chelsea's second-half goal spree with a header.
Torres drove in his second before Juan Mata and Oscar added goals.
