Lorenzo Collacchioni (born 9 August 1980) is an Italian football coach and former player, currently in charge as the assistant coach of Serie D club Pistoiese.
A former defender, he started his career with hometown club Fiorentina. In 2000, he was part of the deal of Marco Rossi to A.C. Fiorentina. He was valued for 1 billion lire (€516,457).[2] [3] However, Collacchioni joined Avellino from Salernitana in the same transfer window. Collacchioni also never returned to Serie A nor Serie B again for the rest of his career. In 2014, he joined Eccellenza Tuscany club Porta Romana.[4] However, in the same transfer window, he was signed by Serie D club Siena.
After retiring as a player, Collacchioni started a career as a coach in the amateur leagues of Tuscany.
After working as a youth coach for Fucecchio, he was promoted to head coach in May 2019.[5] After two seasons with Fucecchio, he left for fellow Eccellenza club San Miniato Basso for the 2021–22 season.[6]
On 12 July 2022, he was unveiled as the new head coach of Livorno, originally scheduled to play Eccellenza but later readmitted to Serie D.[7] On 31 October 2022, Collacchioni was dismissed following a 0–1 league defeat to Montespaccato,[8] only to be called back one day later following a formal request by the team squad.[9] Just a few days later, on 21 November, Collacchioni was however dismissed once again following a 0–3 defeat to promotion rivals Pianese.[10]
On 1 June 2023, Collacchioni was unveiled as the new head coach of San Donato Tavarnelle for the club's upcoming Serie D campaign.[11] Despite the club's ambitions to fight to return to Serie C after having been relegated the previous season, he failed in guiding San Donato into the top positions in the league table, and was ultimately dismissed on 19 February 2024.[12]
On 5 November 2024, Collacchioni joined fellow Serie D club Pistoiese as assistant to new head coach Alberto Villa.[13]
