Park has left United for QPR just as Kagawa begins his Old Trafford career.
â€śThis is only the beginning for me,â€ť Kagawa told the Mirror.
â€śBut Park Ji-Sung is the best player Asia has ever produced â€“ thereâ€™s no doubt about that.
â€śHe played regularly for United for a long time and I canâ€™t be sure how long it will take me to establish myself in the team like him. But I will always work hard to do so.
â€śWatching him play for United motivated me a lot. I began to truly believe Asian players could play in big clubs.
â€śI was expecting we could help each other and play together at United. Itâ€™s a shame that he left.
â€śBut, like Park, I will focus every day on training and do my best to stay here a long time.â€ť
