Borussia Dortmund star Shinji Kagawa is again on Manchester United's agenda.

Nippon Sports says Kagawa is a target for AC Milan and United.

United have been monitoring the Japan international for around a year and it is claimed the midfielder could be viewed as a long-term replacement for Ji-sung Park, but Milan are determined to bring him to Italy.

"I aim to go to a big club one day," Kagawa declared.
