Kagawa has made a tremendous impression since arriving in Dortmund.
When asked to comment on his form, the Japan international replied: "I hope that it will continue. I look forward to the Bundesliga start."
Coach Juergen Klopp was characteristically reserved in his praise: "I was already aware that Shinji can play football."
Kagawa, 21, joined Dortmund from Osaka this summer, at a cost of just €350,000. He has already displaced Tamas Hajnal in his team's starting line-up, having had an impressive pre-season. The talented playmaker bagged a brace yesterday, and nearly grabbed a hat-trick.
Dortmund kick off their 2010-11 Bundesliga campaign this Sunday as they host Leverkusen.
