The Fiorentina striker is looking to prove his fitness as he tries to secure a spot in Cesare Prandelli's 23 man squad and as happy to play in the majority of Saturday's friendly
Montolivo suffered a fracture of his tibia and will miss this month's World Cup in Brazil.
And the Fiorentina forward says Montolivo's injury has been a blow.
"On the pitch the injury didn’t seem that serious," Rossi told reporters. "Obviously we are all sad, no one wanted to see a great player like Riccardo leave the field like that."
Rossi has been unsure of a place in the national team having spent a large spell of the campaign out with a cruciate ligament injury.
However, as he nears full fitness, the 27-year-old put in a bright performance as he played for the majority of his country's 0-0 draw with Ireland on Saturday and the forward spoke of his delight in getting the chance under Prandelli.
"I’m fine, we were a little tired because of the work we’ve done at Coverciano but I’m happy. I played 70 minutes at a high level and there are still two weeks left so we’ll see.
"When you play as a second forward you need to try to get in the spaces between the midfield and the attack. That was my role."
The former Villarreal star was asked for his opinion on his fellow strikers, as he discussed the possibility of a front two of Mario Balotelli and Ciro Immobile or himself and Antonio Cassno.
"Ciro likes to attack the spaces and Mario is more physical.
"Me and Cassano as a pair? First I want to get into the 23!"
