"We aren't in top condition, but nobody is in Italy or Europe," Carletto said. "These games aren't about the condition of the players, but about concentration and experience.
"We have expertise and we are used to this kind of game. It will be a very close encounter, which will be difficult for both teams, but this kind of game brings out an incredible energy.
"Arsenal are a very dynamic side who play attacking football. They play with great enthusiasm, but we know how to show courage and personality.
"This team have always stepped up on these occasions and so I am calm and think that we can do the job."
