Wolfsburg have terminated the contract of defender Arne Friedrich by mutual consent.
Friedrich joined the Bundesliga club from Hertha Berlin last summer but missed the entire first half of the season following an operation on a slipped disc suffered in August 2010.
The 32-year-old has only featured in 15 of a possible 40 league games for the club, failing to make his mark at Volkswagen Arena due to his ongoing injury problems and his struggle to regain fitness.
Manager Felix Magath revealed Friedrich approached him and asked to be released from the deal, which was due to last until June 2013.
''Arne Friedrich came to us and asked us to terminate his contract,'' Magath told www.bundesliga.de. ''We regret his decision, but wish him all the best for the future.''
The Germany international recently undertook a rehabilitation programme with the club's reserve team after the pain resurfaced in June, which stopped him from training with the first team this season.
Friedrich told his website: ''Today I asked VfL Wolfsburg for resolution of my contract.
''Both sides have parted amicably. I will want to use the next few weeks to consider carefully how to proceed and which path I will take.''
Retirement may now be on the horizon for the defender, who made the last of his 82 appearances for Germany in a Euro 2012 qualifier in June.
