Kagawa was great for Dortmund, their driving force for 2 seasons, perfect for their system. he used to score lots of goals and was the best midfield goalscorer in the BL, maybe even in the top 5 leagues. not sure if he would work without wingers stretching the play and creating space for him but we should still get him. if we ever get to use a high pressing 4-2-3-1 with lots of off-ball movements and countering (which i hope in the next 2-3 years) we cant get much better players than Shinji. and getting him now woold save us the work of finding an AM once we get those wingers. so, id say get him and use him in a 4-3-1-2. even if he doesent shine he would still be useful in a marketing way and would explode once we move to a 4-2-3-1...
