He played with Empoli for five seasons, following the club down to Serie B in the 2004–05 season, and subsequently helping the club win promotion back to Serie A in the summer of 2005. In the Serie A, he helped the club reach a surprising 7th position in the 2006–07 season, which gave Empoli a place in the UEFA Cup first round.
Lucchini signed a pre-contract agreement with U.C. Sampdoria in March 2007. He moved to the Genoa-based club in the summer after his contract with Empoli expired. Partnered with Daniele Gastaldello, the club finished as the 4th in the 2009–10 Serie A. In the 2010–11 season, he was rotated with Massimo Volta, with Volta starting 5 out of 6 matches in the 2010–11 UEFA Europa League. Following an injury on 6 March 2011 against Cesena, he rested two matches (13 and 20 March), although he had recovered by 18 March.
He was part of the squad that lost in the semi-finals of the 2002 UEFA European Under-21 Football Championship. Due to the strong performance of Sampdoria in the 2009–10 season, he received his first Italy national football team call-up in August, the first match coached by Cesare Prandelli. However he never received another call-up after that match.
