Chelsea failed to open their defence of the Champions League with victory as Juventus staged a stirring comeback to earn a draw at Stamford Bridge.
Brazilian summer signing Oscar was Chelsea's inspiration with two swift first-half goals on his full debut - the second a spectacular long-range effort that left Juventus keeper Gianluigi Buffon helpless.
But the Italian champions, unbeaten domestically in 42 Serie A matches, demonstrated their pedigree and strength to mount a recovery and earn a point.
Arturo Vidal's goal put them back in contention before half-time and substitute Fabio Quagliarella ensured the points were shared with an equaliser nine minutes from time.
Oscar took the honours for Chelsea with a performance of rich promise on his first start since his £25m switch from Internacional. And the highlight of this opening Champions League group game was the moment the 21-year-old won the hearts of Stamford Bridge with his magnificent second goal.
But even with the lead Oscar gave them, Chelsea were never able to exert complete control and it was no surprise when Juventus eventually drew level via Quagliarella's cool late finish.
Before Oscar transformed the complexion of this game, Juventus had created the two best openings of the half. Chelsea keeper Petr Cech saved at the feet of Claudio Marchisio after he beat the offside trap and Mirko Vucinic shot wastefully wide from the angle after he was played in by Vidal.
Oscar had been on the margins of the action early on - but made himself an instant hero with the Stamford Bridge crowd.
He gave Chelsea the lead with a 20-yard shot that took a crucial touch off Leonardo Bonucci to take it away from the grasp of Buffon.
