MUNICH, July 11 Germany captain Bastian Schweinsteiger will join Manchester United next season, Bayern Munich's chairman Karl-Heinz Rummenigge confirmed in a press conference on Saturday. Rummenigge said Bayern and United have already agreed on an undisclosed transfer fee for the 30-year-old defensive midfielder, who has made 536 appearances for Bayern since his debut in 2002. Schweinsteiger informed the German champions on Friday he wanted a change of scenery after 17 years and is expected to sign a three-year contract with the Red Devils. United confirmed the arrival of what is the first ever German player to join the club in a statement on their official website. Rummenigge said Schweinsteiger had turned down the chance to take part in Saturday's Bayern team presentation at the Allianz Arena and bid farewell to the Munich fans. According to German daily Bild, Manchester United are set to pay between 18 and 20 million euros for the Germany captain, but the transfer deal is not yet completed as Schweinsteiger has yet to have a medical check. Rummenigge insisted there is no truth to reports Schweinsteiger is leaving Bayern because of problems with coach Pep Guardiola. Schweinsteiger comes to Old Trafford with a vast wealth of experience having helped Germany win the 2014 WC and has lifted the German league title eight-time with Bayern. He was part of the Bayern team which won the 2013 treble of Champions League, Bundesliga and German Cup titles under Jupp Heynckes.
