Manchester United boss Sir Alex Ferguson chasing THREE Borussia Dortmund stars for the summer market. The Daily Mail says Ferguson is favourite to land attacking midfielder Shinji Kagawa but is also lining up moves for Poland striker Robert Lewandowski, who scored a hat-trick in the German Cup final, and defender Mats Hummels.

Contract talks with Lewandowski have broken down and his agent Maik Barthel said: "The offer from Dortmund is not enough and I can confirm there is interest from Manchester United."

It is also understood Hummels's father Hermann, who acts as his agent, has been invited to Manchester for talks.
