He later joined Juventus in 2010, where he mainly served as a back-up to Gianluigi Buffon, winning four consecutive Serie A titles with the club as well as the Coppa Italia.

Storari made his Serie A debut on 12 September 2004 in a 0–0 away draw against Parma FC, as the newcomer club went on to finish in seventh place.

In the following seasons he remained the starter, as Messina nearly relegated in 2005–06 after only being reinstated after the outcome of the 2006 Italian football scandal, but eventually dropping down a level the following year, as last.

On 3 July 2007, reports surfaced that Milan were close to sending Storari to La Liga side Real Betis, on a one-year loan.

In the last five minutes of play, he made a double save on Rodrigo Palacio first and then Mauro Icardi to keep his team's 2–1 lead and secure the away win.

[22] After his contract with the club expired at the end of the season, Storari became a free agent in the summer of 2018,[23] after which he subsequently retired from professional football.

[24] Storari was never capped for Italy, although he was selected as third-choice by national boss Marcello Lippi for a 2006 FIFA World Cup qualifier against Slovenia in October 2005.

[25] Storari was known to be an extremely reliable goalkeeper and a consistent shot-stopper, who was gifted with good reactions and who inspired a sense of confidence in his back-line; he was also adept at stopping penalties.
