The Japanese midfielder was a revelation at former club Borussia Dortmund, scoring 17 goals in the Bundesliga last season.
He has not achieved as much success in the Premier League and has, of late, not been utilised too intensively by manager Sir Alex Ferguson with the likes of Danny Welbeck, Antonio Valencia and even Wayne Rooney being preferred for the midfield positions recently.
And Kagawa himself admits that he has not been good enough, referring communication and other adaptation problems.
He was left out altogether for United's 4-2 win over Stoke on Saturday although the midfielder is sanguine about his first-team prospects and accepts that he needs to establish his place by performing in matches in the future.
"To be honest, I don't believe I have yet cemented my place [in the team]," a frank Kagawa told Kyodo News.
"There is not one game that I can be satisfied with the way I played over the 90 minutes. I still feel I need more time to adapt.
"It is fate for any player that plays for a big club and I am trying to draw on the positives.
"I need to communicate better so I can get my timing right when asking for the ball and things like that.
"But more importantly I need to push and show my strengths. You gain trust when you deliver results."
Kagawa could get a chance to improve his goal tally of two goals from seven appearances when United take on Braga in their Champions League Group H clash on Tuesday.
