Manchester United's attacking midfielder Shinji Kagawa has conceded that he must improve his strength to become more effective in the Premier League.
Some pundits have suggested that while the 24-year-old has ability, his small frame will make it difficult for him to succeed in England.
However, Kagawa has expressed his determination to improve upon his weakness.
"I think I can still improve my strength. I'm not the tallest or biggest player so I have to move my body more," he told the Japanese version of the club's official website. "Smaller players in the Premier League are very good at using their bodies [to get past the opposition] 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."
The former Borussia Dortmund player has made nine Premier League appearances this season, but he is yet to find the net.
