The 23-year-old, substituted after an hour last Sunday in Unitedâ€™s 1-1 draw at Tottenham, concedes he has found it tough going in England and knows he must improve on his current form.
â€śIâ€™m really feeling that I need to perform better,â€ť said Kagawa. â€śIâ€™m not satisfied with what I have done here at all.
â€śItâ€™s a big and really famous club in the world and I need to overcome lots of pressures and be mentally stronger.
â€śUnfortunately I got injured, but I have to be better and grow as a player a person, in terms of contributing to teamâ€™s wins and succeeding here.â€ť
