Borussia Dortmund are considering a bid for Manchester United playmaker Shinji Kagawa, according to reports.
The Japan international moved to Old Trafford from the Bundesliga outfit two years, but has struggled to nail down a regular place in the first XI.
After Louis van Gaal's admission that his Manchester United squad is "unbalanced", The Independent has reported that Kagawa's former boss, Jurgen Klopp, is ready to put together a bid to bring the 25-year-old back to Germany.
Kagawa scored 21 goals in 49 appearances for Dortmund between 2010 and 2012.
