According to German Sky Sports, Hertha Berlin, Bielefeld and Eindhoven are interested in renting Bayern Munich midfielder Fehn.
The report claims that if a suitable offer is received within the next 48 hours, Bayern Munich will allow Fehn to leave the team on loan.
Bayern Munich is about to sign Roca from the Spaniard, so Fein will not get too many opportunities in the new season.
Fehn, who is only 21 years old this year, joined the Bayern Munich youth academy in 2006, and he was loaned to Hamburg last summer.
Fehn performed well in the Bundesliga last season. He returned to Bayern Munich this summer. He has not played for the first team this season.
