Manchester United have announced the signing of Borussia Dortmund midfielder Shinji Kagawa.

Negotiations have been on-going with the Japan international for a number of weeks.

The deal is subject to a medical and work permit, although this is thought to be a formality.

Kagawa is currently on international duty and played in Japan's 3-0 World Cup qualifying round victory over Oman at the weekend.

"Manchester United is delighted to announce that it has agreed terms with both Borussia Dortmund and Shinji Kagawa for his transfer to the club," said a United statement.

"The deal is subject only to the player medical and obtaining a UK work permit. These conditions are anticipated to be completed by the end of June.

"Further details will be announced in due course."
