The Old Lady were paired with the Blues in the Champions League last 16 draw on Friday.
“We all know what happened when we were drawn against Real Madrid and Zenit in the group stage and we came out of that,” Secco told Sky Sport Italia.
“We went to Madrid and did the double over them and so we can play against any team.
“We are not afraid of any side in this competition and we have possibilities.
“We respect all the teams but we will play our own game.
“It will be a speacial game for Ranieri. He accepts the draw with tranquility. I haven’t spoken to him about it but I know he will be fine. This is football and it throws these things up.”
