Manager Sir Alex Ferguson is now planning to send the side’s team of scouts to check out the 22-year-old rising star in Dortmund.
The Japanese star found the back of the net eight times in 17 appearances in the Bundesliga top division since his arrival from J-League side Cerezo Osaka before breaking his right foot in January.
Kagawa has also stated that he will not deny rumours of him playing in the Barclays Premier League next season.
If I get a formal offer, I’ll be strongly interested in listening to what they have to say.
The Premiership is one of the leagues I want to challenge. If it is Manchester United, I’ll be still more eager to go and try how much I can do there.
The Red Devils will face strong competition from Juventus, Atletico Madrid, Villareal and Tottenham Hotspur if they are to win the race for Kagawa’s signature before the transfer window ends.
Sir Alex Ferguson is also said to be interested in bringing Tottenham Hotspur star Luka Modric to Old Trafford by the start of next season. The Croatian playmaker is seen by the Manchester United boss as the ideal replacement for the retired Paul Scholes.
