Borussia Dortmund defender Mats Hummels is a target for Manchester United boss Sir Alex Ferguson.

The Mirror says Ferguson sent his brother and chief scout, ­Martin, to watch Hummels in action for their country in the Germany's goalless draw with Holland in Amsterdam on Wednesday.

He signed a new five-year deal in the summer, but insisted on certain get-out clauses and harbours an ambition to play in the Premier League.

Dortmund rate Hummels at £25 million.
