Rummenigge slams Manchester United over Schweinsteiger
The World Cup winner, who recently announced his international retirement after Germany lost in the semi-finals of Euro 2016, has been marginalised at Old Trafford only one year after his €9million move to England.
Rummenigge has been stunned by Schweinsteiger's exclusion from United's first-team plans amid reports he has been told to train with the reserves.
The Bayern executive chairman feels the 32-year-old's treatment will make other big players think twice about joining United.
"When I read that I could hardly believe it," Rummenigge told Bild.
"One or two players are going to think long and hard in future about whether they want to go to such a club.
"Nothing like that has ever happened at Bayern Munich and it will never happen."
Schweinsteiger made just 18 Premier League appearances last season as he struggled with form and injury.
