The Japanese midfielder, who joined the club from Borussia Dortmund earlier this summer, insists that he is getting better with every training session and that scoring more goals will be a target for him at his new club.
Kagawa told reporters: "Every time I practise with my teammates is satisfying. When I get used to my new surroundings more I'll do even better.
"I know most of them know I could do better, and bring out their strong points.
"I feel as though I should be making more chances to get goals."
