Manchester United midfielder Ji-Sung Park has tipped Shinji Kagawa to make a positive impact at Old Trafford.

The 23-year-old Japanese international recently completed a move to United from Borussia Dortmund for around £14m.

"I know United have agreed a deal for Kagawa and I'm happy because we're signing a good player," Park told the club's official website.

"Manchester United is a huge club and every season we sign new, world-class names.

"I hope Kagawa shows how good he is next season and I think he will do."

Kagawa is the first Japanese player to sign for the former Premier League champions.
