Shinji Kagawa insists he will turn his focus to his potential move to Manchester United only after this month's World Cup qualifiers with Japan.
United announced on Tuesday they have agreed terms with Borussia Dortmund
The deal is thought to be worth an initial £12million, which could rise to £17m with add-ons.
The 23-year-old has stressed he is yet to put pen to paper on a contract with the Red Devils and is focused on performing with his country.
