Japan manager Alberto Zaccheroni has claimed that new Manchester United signing Shinji Kagawa has all the attributes needed to succeed at Old Trafford.

Kagawa is believed to be ready to sign for Sir Alex Ferguson's side in the coming weeks after United agreed a deal for the midfielder.

Zaccheroni is confident that the 23-year-old will impress the fans at United and develop into an integral player for the Red Devils.

"I haven't offered him my congratulations yet. I've only said to him 'good luck' because this is just the start for him," said the Italian.

"I know he'll need results to be deemed a success at Manchester United,

"But I fully expect to congratulate him three years from now because he clearly has the mental strength and the technical ability to make it there."

Kagawa will become the first Japanese player to feature for Manchester United.
