Shinji Kagawa has decided that he needs to quit Manchester United in January in order to gain regular game time after failing to win over David Moyes.

The 24-year-old struggled to make an impact in his first season at Old Trafford and has once again found himself on the sidelines since Moyes took charge in the summer.

Kagawa has started just two games this season and was once again on the substitutes' bench as Manchester United secured a 3-1 win over Fulham at Craven Cottage,

After finding himself consistently left out of the starting XI, the Mirror reports that he has informed team-mates that he wants to leave the club in January.

Kagawa is aware of how important it is to play regularly this season with Japan having qualified for the World Cup in 2014.

While many supporters have called for the creative midfielder to gain more regular action he has struggled to convince Moyes that he can be effective in the Premier League.

The emergence of Belgian teenager Adnan Januzaj has also further complicated matters as he has been used consistently on the left of midfield, the one position that Kagawa had been used in at United.

There is sure to be plenty of interest in the Japan international with former club Borussia Dortmund having stated their interest in re-signing the midfielder.

Dortmund Jurgen Klopp is a huge admirer of Kagawa and would undoubtedly be keen to bring him back to Germany after selling him for £17m in the summer of 2012.

Manchester United are expected to make numerous signings in January after failing in bids to sign Cesc Fabregas, Ander Herrera and Leighton Baines

Should they cash-in on Kagawa then the funds may well be used to bring a new creative midfielder to the club, a role they have struggled to fill in recent years.
