Bundesliga leaders Bayern Munich have bolstered their defensive options by signing Hoffenheim team mates Sebastian Rudy and Niklas Suele for next season, the German champions said on Sunday. With captain Philipp Lahm and Spaniard Xabi Alonso nearing the end of their careers, Rudy, 26, will provide another option in defensive midfield, while 21-year-old Suele will be charged with plugging holes in Bayern’s central defence.
