ANALYSIS Frey has been with Leverkusen since joining the youth team in 2004, and apart from a season-long loan at Kaiserslautern during the 2016/17 season, he spent every season with the Werkself. He found playing time with the senior team quite hard to come by, having only made 12 Bundesliga appearances. Frey will likely switch to a team that will offer him more playing time.
