Born in 1999, the 21-year-old spent his youth career playing for the likes of French sides FC Issy-les-Moulineaux and FC Nantes before he was acquired by the Latvian club in March of 2019.
Scoring five goals and providing two assists in 20 appearances in all competitions, Charpentier was then sent on loan to Serie C side Avellino ahead of the 2019/20 season. He had done decently well (scoring six goals in 17 appearances in all competitions) before rupturing his cruciate ligament in December 2019; he even caught the attention of Napoli and Roma.
It is reported that Lazio’s goal would be to sign Charpentier outright and send him directly to the Serie B with Salernitana to keep a close eye on him and monitor his growth. The Granata are the second club Biancocelesti President Claudio Lotito has ownership in.
