Manchester United midfielder Shinji Kagawa has vowed to improve after struggling to hold down a regular place at Old Tafford.
The Japan international has not demonstrated the form he showed at Borussia Dortmund that prompted United to spend £17m on his signature in the summer of 2012.
And Kagawa admits he's well aware that he needs to step up his game if he's to earn a place in David Moyes's starting eleven on a consistent basis.
"I think I can still improve my strength," he told ManUtd.jp. "I'm not the tallest or biggest player so I have to move my body more.
"Smaller players in the Premier League are very good at using their bodies and that's what I will continue to do.
"I realise the Premier League is a very tough league and I know I have to be stronger."
Kagawa has shown flashes of the technique that led many to predict he would become a Premier League star. But his inconsistent performances, both under Sir Alex Ferguson and Moyes, have hurt his first-team chances.
To be fair to the former-Dortmund star, he has often been played out of position on the left-hand side.
In the Bundesliga, he shone brightest in behind the striker in a creative role. He was held in high regard in Germany - Dortmund boss Jurgen Klopp was certainly upset to lose him when he left for United.
Now United fans must hope he begins to find his feet at Old Trafford.
