The move would have been a surprise to fans, as transfers between Chelsea and Liverpool are rare, and Wirtz is still settling into his new team.
In his first season with Liverpool, Wirtz made eight goal contributions in 33 league appearances, showing glimpses of his former form with Bayer Leverkusen.
He started 40 of his 49 matches in all competitions, scoring seven goals and providing eight assists for manager Arne Slot.
