In a game of fluctuating fortunes Posh trailed 1-0, but led 2-1 and 3-2 before securing a 4-3 win with a brilliantly taken last-gasp penalty from Ricky-Jade Jones.
There was however a clear man-of-the-match as winger Abraham Odoh bagged a first-half hat-trick and was also brought down for the match-winning penalty.
Ratings Key: 10-Out of this world, 9-Outstanding, 8-Very Good, 7-Good, 6-Okay, 5-Poor, 4-Stinker.
