On 29 August 2012, after training with Grêmio Barueri Futebol in his country and going on trial with A.S. Varese 1910, even signing with the latter, Rubinho joined Juventus F.C. on a one-year deal. During his spell, he played second-fiddle to Gianluigi Buffon and Marco Storari, although he became known as a key dressing room personality for the Turin side. He made his competitive debut on 18 May 2013, coming on for Storari in the 80th minute of a 2–3 away defeat to U.C. Sampdoria on the final match of the season as the club had already been crowned champions; subsequently, he renewed his contract.
