Italy coach Carlo Recalcati admitted his players are tired with four days to go before the start of the EuroBasket in Serbia & Montenegro.
Recalcati was disappointed with his team's 75-83 defeat against France in their last warm-up game in Milan.
The Azzurri were unable to hold down a team that played without their top NBA star Tony Parker.
"We are quite tired at the moment," said Recalcati.
"We are probably the oldest team going into the EuroBasket tournament and we haven't quite adapted to this situation."
Italy, who won the silver medal at last year's Olympics and finished third at the EuroBasket in Sweden two years ago, begin their European adventure on Saturday against Group A rivals Germany.
It's no surprise the Azzurri players are concerned about their chances with the team yet to hit top form.
"We are a tired team," admitted Italian guard Gianluca Basile.
"We really didn't threaten France at all, we let them play and have easy shots.
"I believe we have taken a step backwards from the Acropolis tournament and it's going to be hard.
"But it's up to us to change this and hopefully we can do it at the right time."
