Dortmund midfielder Shinji Kagawa has been officially signed for Zaragoza. The Japanese talent left the Black Yellow with 2 Bundesliga titles, 2 DFB-Pokal trophies, 60 goals and 55 assists in 216 games.

Shinji Kagawa once transferred from BVB to Man Utd in 2012 and then lost his best form in the following 2 seasons. After that, he returned to Dortmund in 2013. What if he had never left? Would he be better off?
