The coach apprehends the tough task on hand at the Artemio Franchi but says that going on the offensive is the best approach in what he describes as the most important game
The two sides confront each other in Group C of their Euro 2012 qualification campaign, with the hosts needing a victory to confirm their automatic entry into the finals in Poland and Ukraine next summer.
On the other hand, Slovenia are second in the group, eight points behind Italy and level with third-placed Serbia, who have played one game less.
With Estonia just a point behind them in fourth place, the visitors need to get a result from the Stadio Artemio Franchi, and Kek wants his side to garner all three points.
“We are aware of Italy's strength," said Kek in the pre-match press conference on Monday. "They are one of the strongest teams in the world, but we are very motivated and will try to win.
“Losing at home [2-1 to Estonia on Friday] is a problem, so I'm happy to play away even if [winning in] Florence is perhaps mission impossible. We have a young team and the defeats to Northern Ireland and Estonia were heavy.
“We played badly [on Friday] but this is football and you cannot go on an infinite run of results. Tomorrow [Tuesday] we will try to recover for what is the most important match of the entire group.
“Our goal is three points, so we will have to attack and score.”
In the other two games in the group on Tuesday, Serbia host the Faroe Islands in Belgrade, while Estonia entertain Northern Ireland in Tallinn.
