In January 2010, he was signed by Serie A club Parma in co-ownership deal as part of the deal that Daniele Vantaggiato went to the opposite direction. The deal of Vantaggiato was the registration rights of Baccolo plus €1 million cash. Both club also retained the 50% registration rights. Half of Baccolo's rights was valued for €1.5 million and Vantaggiato for €2.5 million at that time,. made both club mutually had a selling profit despite transfer spending increased. However the transfer fee would amortize over the contract length instead (4½-year for Baccolo, €666,667 a year).
