Storari has warned Juve not to focus entirely on keeping City captain Carlos Tevez quiet.
He said: "Tevez is a great player, but he isn't the only one.
"Manchester City have spent a lot this summer to try and win. We know that in these games we have conceded many goals and we must improve in defence.
"It takes the right balance on the pitch and we are working a lot to follow the mister's instructions,"
