Poor first half.
Inter pressed well at times and their front two were occupying Juve whole back four, which meant they were able to find spaces elsewhere relatively easily.
Marchisio and Vidal played too high up. This made it harder for Juve to keep the ball and more dangerous when they lost it.
Not sure the change to 3-5-2 really changed the game. It made sense from a defensive perspective because it made it easier for Juve to get tight to Milito and Forlan without having the whole defence dragged out of shape.
However, the goal came so quickly after the change and, was such a gift, so I'm not sure the change in shape changed the game half as much as the goal did.
Inter's heads then went down and it was pretty straightforward for Juve to see the game out and they really ought to have scored more goals than they did.
Good showings from Caceres, Buffon and Vidal, with Caceres probably edging it for man of the match.

Ranieri helped us a lot. He did fine by putting Poli on Pirlo and we really struggled, especially because Inter's fullbacks were successfully neutralizing our wing play. Then out of nowhere he took off their most energetic players Obi and Poli and replaced them with a wingback and a striker. He just gave the midfield to us because all he had there was the awful and slow Stankovic.
Even if Del Piero didn't score so soon after Ranieri made those subs, it was still gonna be a Juve win and easy 20 minutes.
He really did the worst possible thing and made it sure that Inter won't be a threat anymore.
In theory it was a bad change because it robbed Inter of energy and focused more play thourgh the middle - where 3-5-2 is strongest.
However, in practice, between Juve getting the goal and Inter already being pretty demoralised, I'm not convinced it made much difference.
Ranieri set up his team well and was let down by his players. Poor finishing in the first half and abysmal marking in the second decided the game.
