Birmingham City boss Harry Redknapp has taken aim at MAnchester City manager Pep Guardiola.

Redknapp wrote for the London Evening Standard: "Guardiola is just about the only manager in the world who could avoid the sack at Manchester City if they finish outside the top four and fail to win a trophy.

"That would be a disaster for a club which spent about £175million last summer, having lifted the League Cup and qualified for the Champions League before getting rid of Manuel Pellegrini.

"Instead of challenging for the title straight away, as most people assumed City would because of Guardiola's impact, they are scrambling to make the top four — and that is why tonight's Manchester derby is bigger for them than it is for United.

"Of course, if you have Guardiola's cv, then any board would think twice about firing him, but that shouldn't hide the fact they have fallen well short of expectations this season."
