Kagawa will be United's first signing in the transfer window and only a medical seems to be in the way before he is unveiled as a Red Devil.
But he is currently with the Japan side where he will bid to help the nation achieve qualification for the upcoming World Cup in Brazil. Japan have been drawn in a tough group alongside Iraq, Jordan, Australia and Oman.
Kagawa was part of the side that won their opening game in Group B against Oman. Kagawa notched an assist in the match and the Japanese need to end the group in the top two in order to ensure automatic qualification.
Should they come third, they will have to play in a qualifying play-off match against the third-placed team in Group A and then play a team from South America for a place in the 2014 World Cup.

The 23-year-old insists that the deal is not done yet and revealed that he is currently only concerned about preparing for Japan's upcoming game against Jordan on Friday.
"The transfer is not complete for the time being. I have yet to sign the contract," Kagawa told Kyodo News after training with his national team on Tuesday.
"The team and I are fully focused on the next two games.
"It's better if we talk about (the transfer) after those matches. I want to focus on playing well over the next few weeks."
The AFC Asian Cup winners will also play Australia on June 12 in a rematch of last year's final.
Kagawa scored 21 goals in 49 appearances for Dortmund last season helping them win a league and cup double.
