The 23-year-old spent last season on loan at Hellas Verona, but the club decided against making the deal permanent.
However, FC Koln have had a bid of £1.8m accepted and could confirm the deal this weekend, reports Koln-based newspaper Express.
Sorensen, who has 15 caps for Denmark Under-21s, joined Juventus from Lyngby BK in 2010.
