Rodrigo Palacio began todays training session apart from the rest of the team. The player isn’t expected to be a part of the squad that will travel to Iceland to face Stjarnan, this due to a hurting leg after returning from the World Cup. Palacio is waiting to return to his best of form and this means Icardi will surely start the game. The team will leave Italy tomorrow according to Sky Sports Matteo Barzaghi.

Unfortunately, you will be dissappointed as Mazzari would not play both Icardi and Osvaldo. I am guessing that he will try again the lone striker formation. But, there may be a chance for Osvaldo to join Icardi in the second half.
Icardi and Osvaldo from the first minute.
I agree. I thought we looked a lot more dangerous with Osvaldo in there too
