Pep Guardiola has not been through a moment like this in his managerial career.
Manchester City have lost nine matches in their past 12 - as many defeats as they had suffered in their previous 106 fixtures.
At the end of October, City were still unbeaten at the top of the Premier League and favourites to win a fifth successive title. Now they are seventh, 12 points behind leaders Liverpool having played a game more.
It has been an incredible fall from grace and left people trying to work out what has happened - and whether Guardiola can make it right.
