Shinji Kagawa is confident he can rise to what he describes as 'the greatest challenge' of his career, after joining United.
The attacking midfielder has made a meteoric rise to prominence, having won back-to-back Bundesliga titles with Borussia Dortmund after previously featuring in the second tier of Japanese football, and he is keen to continue the upward trend of his career to date.
"I'm happy to be here and every day I'll take the chance to improve myself and move further up," he told the world's press at his Old Trafford unveiling. "It's definitely the greatest challenge of my career and I hope to learn and improve every day.
"I've always said I have to improve my playing qualities; now I've been here a bit I can really feel the difference. It's a top level club and environment, and when the other internationals join us it will be even better.
"I definitely feel the attention of the media globally now. I'm a member of a great club at Manchester United. I think I can handle the pressure and am pretty confident I can adapt to the style of the Premier League.
"Everything here shows me it's a really big club and it's a great honour to play here. I want to really contribute by achieving concrete results."
The versatile playmaker, who also confirmed his preference for playing in a central attacking role, admitted that he is keen to quickly learn English in order to hasten his assimilation to life at his new club.
"Language is very important to me," he said. "I'm very motivated to learn English; I hope I can learn it quickly so I can communicate with my team mates very soon."
Sir Alex Ferguson feels United's upcoming DHL Tour will provide the newcomer with the perfect setting to help him adapt to his new team-mates.
