Japan international Shinji Kagawa backed his ability to handle the pressures associated with playing for Manchester United, saying on Thursday his move was the "greatest challenge" of his career.
The 23-year-old is United's first high-profile signature of the close-season with his switch from German champions Borussia Dortmund and the move has generated huge media attention, especially in his native Japan.
"I'm a member of a great club at Manchester United," Kagawa told the club's website www.manutd.com.
"It's definitely the greatest challenge of my career and I hope to learn and improve every day.
"I think I can handle the pressure and am pretty confident I can adapt to the style of the Premier League.
"I definitely feel the attention of the media globally now."
Kagawa made his name at Dortmund as an attacking playmaker where he made 49 appearances and scored 21 goals in two glittering seasons that yielded back-to-back Bundesliga titles.
His new manager Alex Ferguson said he expects Kagawa to adapt quickly to life at the club and predicted his impact would be felt early on.
