The England midfielder has agreed terms and passed his medical last week and the deal is expected to be signed on Tuesday, according to the Manchester Evening News.
Hargreaves said: “I have been lucky to play in big games and win some wonderful titles. I have won everything a player can in Germany – titles, the Champions League and even the World Club Championship.
“It is now about experiencing that somewhere else and I can’t wait to start over again. The prospect of adding a Premiership winner’s medal to my collection is incredibly exciting.”
