The agent of Shinji Kagawa says Juan Mata's arrival at Manchester United hasn't upset him.
The Japan international appears on the outer after United's swoop for former Chelsea midfielder Mata, but Thomas Kroth insists Kagawa wants to stay.
The midfielder has been linked with a return to Borussia Dortmund after Jakub Blaszczykowski suffered a serious knee injury this week.
But Kroth insisted: "Shinji wants to stay. He will not leave Manchester United in January."
