Manchester United expect to complete the signing of Borussia Dortmund ace Shinji Kagawa next week.

The Daily Star says United have agreed a fee with Borussia Dortmund of around £14m, which may rise to £20m depending on ­appearances and add-ons.

Kagawa, 23, is on ­international duty with ­Japan - who face World Cup home qualifiers against Oman and Jordan over the next week - and has been unable to discuss terms.

But the ­attacking ­midfielder is expected to agree a five-year ­contract worth £60,000 a week when he returns to ­Manchester for further talks.
