I foresee a very cagey game in which neither team is prepared to take risks to win.
Atletico will battle away, get crosses into the box, and look to win the game with a set-piece.
Juve will look to keep the game slow, keep men behind the ball, and hope for a moment of quality from an individual to win the game.
I'm curious to see whether Allegri will look to use Juve's excellent midfield to try and dominate in that area and control the game from there or if he will be content to drop back a little and look to hold Atletico at arm's length.
And will Juve make much of an effort to prevent Atletico getting crosses in? 3-5-2 is not a good shape for doing that because of generally being outnumbered on the flanks. Having three centre-halves in the box should, of course, leave you in a good position to deal with any crosses, though.
Juve have to back themselves to defend set-pieces properly. They are going to be playing Caceres/Ogbonna, Bonucci, Chiellini, Lichtsteiner, Pogba and Llorente. If you can't defend high balls with that sort of height and physical presence in your team, there is something badly wrong.
I'll be interested to see what the marking is at set-pieces. Mandzukic and Godin are big threats. Chiellini will take one of them, but which Juve player is designated as the number two? Bonucci? He's big, but not a great marker (in fact, I believe it was him marking Godin when he scored against Italy at the World Cup). So I'd see the marking of Atletico's second biggest threat as an issue.
My answer might be to have Lichtsteiner mark Godin, but just with a view to blocking him rather than actually winning a header against him. Then have Llorente and Pogba strategically positioned (one at the front post and one in the middle of the goal) to be free from man-marking duties and simply focus on going and aggressively trying to win the first header to clear the ball.
Because of Atletico's threat from crosses, I may well play Evra rather than Asamoah. I believe he is better at defending the back post on crosses.
