Manchester City are concerned midfielder Gareth Barry could miss the start of the new Premier League season with the same injury that ruled him out of Euro 2012 for England.
The 31-year-old is set to see a specialist in Germany concerning the torn muscle in his lower abdomen that he suffered during England's friendly with Norway prior to the tournament, according to the Daily Mail.
City have turned to Dr Ulrike Muschaweck, a leading specialist in abdominal muscle injuries in Munich, after fears had been raised the injury was still causing him trouble.
There is a possibility that an operation could be required after an initial examination took place last Monday, meaning the former Aston Villa star could be out for up to two weeks.
City chief Roberto Mancini – who yesterday agreed a new deal to remain as manager for the next five years – will want Barry back in action as soon as possible as his side look to defend their title at the first time of asking.
The defensive midfielder played an important role in City's success last season, and the medical staff at the club have decided action was necessary when it became evident more than rest was needed to cure the injury.
Dr Muschaweck has prior history of dealing with these kind of injuries with Premier League stars, having treated Michael Owen while he was at Newcastle. Muschaweck was able to repair a torn adductor muscle which had kept the former England striker out on the sidelines.
