Well, I think the key issue in the this game is not so much that Juve play to win, but just that they go out and play Galatasaray.
By that I mean that they should be engaging them in midfield and looking to control the game there, rather than looking to sit deep and soak up a lot of pressure.
Setting out to control the game is the best way for Juve's best players to be able to have the biggest influence on the game, where I'd suggest sitting back and allowing Galatasaray the ball increases the chances of Drogba or Sneijder coming up with something good or conceding a goal from a set-piece.
And I think it would be fantastic if Galatasaray choose to mirror Juve. It would remove so much of the tactical aspects of the game and reduce the game to one-on-one confrontations all over the pitch and that should suit Juve perfectly, what with them having better players than Galatasaray.
