The Juventus midfielder is brimming with confidence ahead of the Azzurri's match versus Republic of Ireland on Monday.
The Italians currently sit third in Group C with two points from two games, but the Juventus midfielder is hopeful that the Azzurri will beat Republic of Ireland to book their ticket for the quarterfinals.
"Although we're third, we have a great chance of qualifying. We just need to worry about our own game and what we must do to beat Ireland," Marchisio said to UEFA.com. "The squad is united. We've got a great group here, even if we didn't manage to win against Spain or Croatia. We'll try to get through the group by giving it everything we've got.
"It won't be an easy match, even if Ireland are out already, because they are a very gritty side. We played them last summer and it didn't go well. That was a friendly match and our approach will be different this time, as will the result I hope."
Monday's encounter in Poznan is scheduled to kick off at 2:45 p.m. ET.
