Ralf Rangnick says he respects Manchester United fans' protests outside the club's Carrington training complex.
Police were called after around two dozen supporters gathered on Isherwood Road, which leads up to Birch Road, a country lane the training complex is situated on.
The usual entrance to the training complex was closed and visitors were redirected to the rear entrance that is reserved for first-team players when they arrive for training. Bedsheets unfurled by the supporters read, 'Disgrace not fit to wear the shirt' and 'Glazers out'.
