Three reasons why Peterborough will knock Chelsea out of the FA Cup

Failed rotation

Antonio Conte has so far struggled in his previous attempts to rotate his side.

The Blues crashed out of the EFL Cup to West Ham United in the fourth round after Conte made six changes to his side.

The Italian manager has decided against making changes to his side recently as he has commonly stuck to a regular starting 11.

Peterborough can easily take advantage of a changed team that will be lacking both fitness and match sharpness, which could see them through to the fourth round draw.
