Pep Guardiola has warned he will quit Manchester City in a month's time if he cannot turn around the club's torrid form.
City go into Sunday afternoon's Manchester derby with just one win in 10 and suffered a miserable 2-0 defeat at the hands of Juventus in midweek, leaving them at risk of an early Champions League exit.
He has never before faced a crisis of this magnitude in his managerial career and City have slipped to fifth in the Premier League behind Nottingham Forest.
