Manchester United manager Sir Alex Ferguson has been spotted in Berlin scouting Shinji Kagawa as Borussia Dortmund take on Bayern Munich in the German Cup final.
The Japanese midfielder has been linked with a number of clubs across Europe following his move to the Bundesliga in 2010.
The 23-year-old opened the scoring for Dortmund as they clinched a 5-2 victory over their rivals at the Olympic Stadium.
The German champions are expected to want over £10m for Kagawa in the summer.
