Manchester United midfielder Shinji Kagawa has revealed that he is unhappy with his performances this season following his summer move from Borussia Dortmund.
Kagawa had made a solid start to the season following his summer switch to Old Trafford, but didn't feature at all during Saturday's 4-2 win over Stoke in the Premier League.
And speaking to Kyodo News, the Japan international conceded that he is struggling to adapt to English football.
"To be honest, I don't believe I have yet cemented my place [in the team]," Kagawa said.
"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."
The 23-year-old recently admitted that he had been told to work on his body strength and has reportedly been put on a special fitness routine to assist with this.
The playmaker also admits he need to improve his English in order to help his communication with team-mates.
"I need to communicate better so I can get my timing right when asking for the ball and things like that," he added.
"But more importantly I need to push and show my strengths. You gain trust when you deliver results."
