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

The streak ended

Chelsea’s 13 match league winning streak came to an end against rivals Tottenham Hotspur on Wednesday evening.

The camp’s mood will be the poorest it’s been since their defeat to Arsenal in September.

Grant McCann’s side will want to make the most of any signs of unrest or lack of morale on Sunday.

Peterborough will be thanking both Tottenham and Dele Alli for handing Chelsea a long awaited league defeat.

A win for the Posh would be the start of a real downward spiral for the Premier League leaders.
