Fabio Quagliarella struck a late equaliser to share equal billing with Chelsea FC's Oscar, who had scored twice on his first Blues start to put the 2012 UEFA Champions League winners in sight of another opening-day victory.
Quagliarella, a Juventus substitute, took advantage of some uncertain defending to earn his team a point after Arturo Vidal had reduced the arrears near the end of an exhilarating first half. It marks the first time since 2007 that the London side have not begun their group stage campaign with three points.
With Fernando Torres operating as a lone striker, Chelsea did not give Gianluigi Buffon too much cause for concern in the opening half-hour. They produced some nice approach play, but generally Juventus's three central pillars looked solid.
At the other end the visitors, back among Europe's elite for the first time since the 2009/10 season, took heart from the movement of Mirko Vučinić. It was Claudio Marchisio, however, who came closest when Leonardo Bonucci's long pass sent him clear, Petr Čech dashing off his line to smother the shot. A loose ball from Branislav Ivanović then almost presented a goal to Juventus. Vidal found Vučinić yet he sliced his attempt into the side netting.
The Italian champions should have been one ahead; instead, within four minutes, they found themselves 2-0 down as Oscar, starting in a blue shirt for the first time after five games on the bench, took centre stage. His first, following Eden Hazard's incursion from the left, owed a great deal to the diversion it took off Bonucci's boot.
His second was pure class, however, skilfully taking the ball away from two defenders before bending a powerful drive high beyond Buffon's left hand.
It was a sensational couple of minutes for the Brazilian and his team. The Stamford Bridge crowd rose to salute him but were then silenced as Juventus hit back. Marchisio brought Vidal into contention and with Oscar-like skill he made room before burying a low left-footed strike.
The tempo barely relented in the second half, David Luiz moving in quickly to dispossess Marchisio when danger loomed. Before that Ivanović and Frank Lampard both prompted saves from Buffon. Chelsea appeared to be holding on yet then failed to clear their lines, allowing Marchisio time to feed Quagliarella who shot beneath Čech. The substitute then almost won it for the Turin side as he turned to graze the bar with a curling left-foot effort.
