– Manchester United midfielder Shinji Kagawa speaking to premierleague.com
It was a tough time for me with a lot going on in my head.
I am not happy with my performance for the team at all. I didn't score that much and I also had my (knee) injury.
Despite that, it was great we won the league, I just don't feel that I achieved everything that I wanted.
For me personally, it wasn't a good season.
