It was a masterclass in counter-attacking as Posh held firm in the opening stages before putting the League One strugglers to the sword with some excellent football.
Under fire Will Norris even put in a performance that will likely go some way to winning fans back around.
Here are the PT ratings for the players and the manager.

5. RONNIE EDWARDS
He brought the ball out of defence in a much more positive manner than usual. Some shaky defensive moments, but also some strong ones 6.5. Photo: Joe Dent
6. OLIVER NORBURN
Helped Posh gain control of the midfield with some fine ball-winning and simple passing. Substituted second-half when the game was won 7. Photo: Joe Dent
7. JACK TAYLOR
Some majestic moments on the ball including a superb pass to help create the final Posh goal. Did the dirty work as well 8. Photo: Joe Dent
8. HARRISON BURROWS
Most impressive from the young midfielder who played with great energy coupled with good movement, good positioning and well-timed runs into the area. In the right place to claim a goal 9. Photo: Joe Dent
