Scotland midfielder Scott Brown believes Italy may struggle to cope with the pace of Saturday's Euro 2008 qualifier at Hampden.
Victory for either side would secure their place in next summer's finals, while defeat would eliminate Scotland.
But the hosts for the Glasgow clash are in a positive frame of mind, and Celtic livewire Brown predicted Italy will run the risk of being overwhelmed by Scotland's sheer appetite for the fixture.
Brown told the Daily Record: 'We believe in ourselves and we're not frightened of anyone.
'We play with a lot of energy and enthusiasm. The Italians are older than us and I'm not sure they'll be able to keep up with the pace we set.'
Italy are in Florence until Friday morning, but with the country in a state of shock after the death of Lazio fan Gabriele Sandri, who was accidentally shot by police at the weekend, their focus has been diverted away from the Scotland game.
Manager Roberto Donadoni has reminded his players of the test they face at Scotland's national stadium, and picked out strikers James McFadden and Kenny Miller as players to be wary of.
'Scotland are a very good side but their strength is in the group and that is the same with us,' said Donadoni. 'There are of course individual players who are at a higher level than the rest of the group, such as McFadden and Miller.
'But we will consider the whole team when we are in Glasgow.'
A draw on Saturday would only suit Scotland if France were to lose in Ukraine next Wednesday.
Donadoni predicts his side and Scotland will both be going all out for victory and a ticket to next summer's finals.
The former AC Milan midfielder said: 'In the 25 years I have played and coached, I have never gone into a game looking to draw.
'Scotland cannot expect France will go to Ukraine and lose. For this reason I do not expect they will settle for a draw.'
