Shinji Kagawa has been one of my favourite players in the Bundesliga for the past two years. He has been instrumental for them in their title win last year, and he has put in splendid performances this year as well.
However, the Japanese has refused to sign an extension for the next season, so he will be on his way out.
Kagawa has been linked to Manchester United several times, and the Red Devils are probably the favourites to obtain his signature.
Kagawa plays as an attacking central midfielder for the Borussia outfit, and it would be interesting to see how he would fit into the 4-4-2 formation that Sir Alex Ferguson generally employs.
Perhaps a shift towards a 4-2-3-1 formation might be likely with Darren Fletcher and Michael Carrick occupying the holding positions, Antonio Valencia and Ashley Young/Nani on the wings, Kagawa in the center and Wayne Rooney leading the charge might work.
However, it would hurt the development of the both Javier Hernandez and Danny Welbeck.
I cannot grasp how he would fit in with United, but having such a player at your disposal is certainly a worthwhile investment. He also allows United to tap into the lucrative Japanese Market.
