Atalanta keeper set for debut
Calderoni is poised to deputise for Massimo Taibi (pictured) against Internazionale due to Atalanta's first-choice being suspended after his involvement in a brawl against Torino last weekend.
The 26-year-old joined Atalanta from Monza in 2001 but has yet to figure for the club in the Italian top-flight.
He will be plunged in at the deep end on Saturday but Calderoni is not afraid of facing the fearsome Inter attack.
"I'm not frightened," affirmed Calderoni. "I have just a little tension but I'm charged, too.
"It's the first appearance in Serie A and there are big motivations."
With Christian Vieri injured for Inter, Calderoni has pinpointed Alvaro Recoba as the man most likely to spoil his Serie A bow.
He added: "They have the best Italian attack even if there won't be Christian Vieri.
"Who is the player I fear most? Alvaro Recoba. On free-kicks you have to be lucky. You can try looking at the ball and you hope.
"He's a fantastic player. I met him last summer in a friendly match which Inter won 3-2. I played the second half and who scored? Recoba."
