On 20 January 2010, it was confirmed Serie A giants Juventus had signed Candreva on loan for the rest of the season, for €500,000, with Juventus having an option to buy half of his contract from Udinese at the end of the season. He scored his first Serie A goal, the winner against Bologna, less than ten minutes after coming on as a substitute for Diego. A few days later, he made his debut in European competitions in the Europa League, in the second leg of the club's round of 32 fixture against Ajax, when he came on as a late substitute for captain Alessandro Del Piero.
On 31 August 2010, Candreva signed for Serie A side Parma on a one-year loan deal, for €500,000. Parma had the option to purchase Candreva in a co-ownership deal, but declined to do so.
In early May, Candreva was called up for the training camp prior to the 2010 FIFA World Cup; he was included by manager Marcello Lippi in the 30-man preliminary squad announced on 11 May 2010, but was dropped from the 28-man provisional team a week later.
