Fabio Quagliarella's goal has given Juventus a 1-0 lead against Chelsea at half-time in their Champions League Group E clash in Turin.
In an entertaining first 45 minutes, the first chance fell to the home side in the fourth minute when Stephan Lichtsteiner had his effort deflected onto the post by Petr Cech.
Five minutes later Oscar came close for Chelsea when he skipped past two Juve defenders to release Eden Hazard, only for the Belgian winger to see his shot saved by Gianluigi Buffon.
Thereafter, it was all one-way traffic as Juventus began to assert themselves on the game, Claudio Marchisio forcing out an excellent save from Cech in the 15th minute.
Five minutes later the Chelsea goalkeeper was again called into action, this time from a shot from Quagliarella, before Mirko Vucinic tried his luck on goal but in vain.
Andrea Pirlo too had a shot on target on 25 minutes from a direct free kick, but once again Cech held his nerve.
The Italian champions eventually broke the deadlock and the goal came in the 38th minute.
Pirlo took a shot from outside the Chelsea area that Quagliarella deflected home past Cech.
Antonio Conte's side could have gone 2-0 up moments later had Ashley Cole not cleared a Lichtsteiner attempt off the line.
