Mario Balotelli has been left out of Italy's squad to played the United States as coach Cesare Prandelli cast doubts over the Manchester City striker's state of mind.

Balotelli's omission makes his selection for Euro 2012 a doubt, with former Chelsea and Swansea striker Fabio Borini earning a first call-up in his stead.

Axed: Balotelli scored for Man City at the weekend

'He (Balotelli) still seems a little agitated to me,' Prandelli said. 'When I say we have to reach the European Championship prepared, I mean I don't want to get there with a squad who don't know how to manage tension and provocation.

'I don't want to see players who at the first sign of difficulty commit fouls and get sent off, leaving their teammates to struggle with 10 men. So we have a few months to think about it.'

Borini, 20, is enjoying a fruitful first season at Roma and he notched his seventh goal of the season at the weekend.
