Two goals from captain Matt Godden, a long range effort from Gustavo Hamer and Nathan Thompson’s own goal helped the Sky Blues breeze to victory despite Jorge Grant finding the net with a neat finish of his own before half time for The Posh.
It was a first league win in six for Mark Robins’ team, a run which stretched back to November 6 thanks to an array of postponements throughout December.
Peterborough suffered their 15th defeat of the season – a fourth at home – and have now conceded 48 goals in the league, which is the worst defensive record in the division.
Complete control from start to finish for Coventry
There wasn’t a time in the game when you felt Peterborough were fully on top.
Coventry were on the front foot from the first whistle and didn’t stop pressing until the very end, forcing errors from the opposition and then capitalising on them.
Numerous times, a Peterborough midfielder would get dispossessed and Coventry would fashion a chance from it and, on another day, could have four by half time.
They could have had 10 by the end if it wasn’t for hosts’ ‘keeper Dai Cornell, the woodwork or some poor finishing.
It was almost perfect, with just the goal they conceded the only negative for the Sky Blues to take from the game.
From the back, they were solid and did what they had to do when called upon.
The midfield was perfectly balanced and allowed hardly any space for a Peterborough player to operate on.
And the frontmen were lively, popping up on the ball all over the place to try and create another opportunity or to win it back high up the pitch.
In transition they were great, too, getting back in numbers but then having the energy and urgency to stream forward as often as they could.
A clean sheet would have rounded the day off perfectly but, other than that, it was complete brilliance from City.
Dangerman Godden haunts his former employers
Every time Coventry went forward, they looked dangerous and every player streaming forward looked a threat on the ball.
But skipper Godden, who had a topsy-turvy spell with The Posh, had the opposition defence in the palm of his hands.
Thompson, Josh Knight and Ronnie Edwards couldn’t keep track of his movement and it caused problem after problem for the hosts, who looked shattered ten minutes from the end when Coventry added two more goals.
Godden’s hold up play was also impressive, he was rarely dispossessed and got his team up with play throughout the game, especially as it became more open in the second half.
It was an all-round solid performance from the Sky Blues number 10, who took his tally for the season into double digits with a pair of calm finishes past a helpless Cornell.
Alongside him, Callum O'Hare was a consistent danger throughout the entire game, and his performance deserved a goal.
His quick feet were a constant thorn in the side of The Posh's defenders, and he was able to create a number of good opportunities for his teammates who were usually in acres of space.
Posh were nothing short of abysmal
It may seem harsh to say, but they were.
After half time, Grant flashed a shot into the London Road Terrace as The Posh started brightly.
There next chance of note didn’t come until the 83rd minute, after Coventry had gone 1-3 ahead.
For a team who have picked up big wins at home this season, as well as holding Bournemouth, they approached the game like the away side.
They sat back and allowed Coventry time in the middle to dictate the play, and invited pressure for the majority of the game.
They were so poor defensively, the Coventry players were in so much space more times than not.
When they were in possession, the ball went backwards more times than it did forward which brought further pressure onto the backline.
There was no option forward, which cost Peterborough the second goal when Bali Mumba dallied in possession before being dispossessed as he didn’t want to play backwards.
It was an error for the first goal from Cornell, too, who should have done much better with Hamer’s strike from 30-yards out – but he should have been closed down faster than he was.
When they did look forward, Siriki Dembele looked the most dangerous, but he was more focused on flicks and tricks than playing the ball to a teammate, which earned him some jeers from the away supporters.
And the balls up to a relatively diminutive strike force in Dembele, Sammie Szmodics and Harrison Burrows where too high or too far away which was easy for the visitors’ back three to deal with.
It looked like a cup game between teams multiple divisions apart, that was the gulf between the two today who were in the League One together just two seasons ago.
Both games are 3pm kick-offs.
