Wolfsburg confirm they will not exercise option to buy Barcelona's Alexander Hleb

The attacking midfielder has been unable to make an impact at the Bundesliga side due to injury and will be sent back to Catalunya once his loan expires at the end of the year
Wolfsburg have announced that they will not exercise their option to sign Barcelona midfielder Alexander Hleb on a permanent basis and the 30-year-old will leave the club once his loan deal expires at the end of this year.

Hleb joined Wolfsburg on a six-month loan stint at the start of the season, with an eye on extending his stay at the Volkswagen Arena if both parties were satisfied.

However, Hleb has struggled with injuries since his arrival in Germany and has made only four Bundesliga appearances for the 2009 champions, with Wolfsburg deciding to send Hleb back to Barcelona at the end of 2011.

"This is all very sad. I would really have liked to keep him at Wolfsburg, but his ongoing injury problems simply don't allow it," said head coach Felix Magath on the club's website.

Hleb joined Barcelona from Arsenal in 2008 but has spent the majority of his time on loan at Stuttgart, Birmingham City and now Wolfsburg. He has a contract with the Catalan club until the summer of 2012.
