Manchester City will have to make rapid improvements if they are to qualify for Champions League football after losing 1-0 at Nottingham Forest in the Premier League on Saturday, manager Pep Guardiola said.
Surprise package Forest remained third in the table with 51 points after 28 matches, four points above fourth-placed City. But reigning champions City could drop out of the top four if Chelsea, who are fifth, avoid a loss against relegation-threatened Leicester City at Stamford Bridge later on Sunday.
City's campaign has been hindered by a rash of injuries, with Ballon d'Or winner Rodri, defenders John Stones, Manuel Akanji and Nathan Ake among those sidelined.
