While my hopes are up for Bayern and the Bundesliga (for the 4th CL spot) i feel like Inter is gonna win this. I think this will be the only match in the whole season where Riberys absence will be the decisive losing factor. Zanetti showed his class in 1-1s vs Messi twice already, and i feel like he will also shackle up Robben. With him out there is no other offensive player able to make a difference and solely outplay Inters defense (and not to forget that Rib and Rob linked up very very well in the last games, esp. the cup final vs Bremen). And Inter generally need to focus on only one side anyway.
It also has the tactical downfall of givin Maicon the opportunity for his offensive runs. Maicon had to be helt in the back to keep Ribery at bay, and still i believe the frenchman would have been a nightmare to both Maicon and esp. Lucio (this side seems just muhc more vulnerable than INters left). I dont feel like Altintop can do anything up there, and i also dont believe that the duo of Altintop and Badstuber will be shutting down Maicon (and Etoo) for the whole game.
Key moments for Bayern could however arise when Robben switches to the left. It will be interesting to see if Inter is able to adjust to that midgame. It could then but also give opportunities for Inter to use the open left side with Sneijder and Pandev.
