The Spanish midfielder has agreed a move to the Ligue 1 club after seven years with Liverpool, which included 11 appearances for the first team.
Chirivella made his senior Reds debut as a substitute in the Europa League tie against Bordeaux in September 2015 and featured a further four times that season following the appointment of Jürgen Klopp as manager.
After embarking on a series of subsequent loan spells to gain experience, he came back into the first-team picture during the current season and played six times before the suspension of English football due to the COVID-19 pandemic.
