Accepting competition for places goes with the territory at Old Trafford, Kagawa, who started 17 times during the successful league campaign, realises it will again be a challenge to pin down a place under David Moyes but the attacking midfielder is aiming to impress his new boss.
"Last year, I knew there would be a lot of competition within the team for me to be in the starting line-up," he explained. "I knew it's a big club and it would happen.
"I really need to show results and there are so many things I have to do like work hard every day. I will be playing in my home country tomorrow and I want to focus on the game to be able to perform at my best."
