Good performance overall.
First half was pretty ropey.
Juve's desire to press was good, but the combination of Barzagli often moving very high up to press combined with Pirlo moving forward to try and find space left Juve vulnerable to counter-attacks. That was made worse with a couple of poor give-aways in dangerous situations.
The second half was excellent, though.
Really a dominant, commanding display.
Chelsea were never given a chance and Juve should have scored more goals than they did.
Chelsea's central midfield isn't strong enough to win games against good teams. They are consistently overrun in that area of the pitch when they come up against strong sides.
Their decision to not play with a CF also helped Juve, as Chelsea had no-one to hold the ball up and relieve pressure. That meant Juve were able to be really aggressive, win the ball back early and attack almost continuously up to the second goal
Chiellini was awesome.
