Manchester United's inquest into Sunday's humiliating derby defeat by Man City begins this Monday at Carrington.
Red Devils stars arrived at the club's training ground looking glum this morning, where they will speak with the boss Erik ten Hag and go through exactly what went wrong at the Etihad, where they were battered 6-3 by their rivals.
Ten Hag has encouraged his players and staff to tear into each other on the back of the defeat and to get all problems out in the open. "It's an open door - this performance was unacceptable," the United manager explained on MUTV.
