Posh opened their pre-season friendly account with a 3-1 defeat at Sky Bet Championship side Leicester City.
Peterborough United manager Darren Ferguson will take positives from the performance against a side recently relegated from the Premier League with the Foxes scoring twice in the last quarter of the game to secure a hard-fought 3-1 victory at Seagrave, their plush training complex.
The hosts fielded two different teams in each half, while Posh almost did the same - Lucca Mendonca the exception as he completed 90 minutes at the heart of a youthful back-line.
The first half was lacking in real clear-cut opportunities with the Foxes dominating possession after a bright start going forward by Posh.
Gustav Lindgren did have the ball in the back of the net on the stroke of half-time, but it was rightly chalked off for offside.
In the second 45, there was far more goal-mouth action with Bradley Ihionvien denied by a fine stop from Stevie Bausor, who then tipped a deflected cross from Kyrell Lisbie over the top.
The home side opened the scoring through Louis PAGE who saw his shot deflect past goalkeeper Nick Bilokapic. Bilokapic made a good stop to deny Thomas before Posh responded strongly.
Brandon Khela dispossessed Conor Coady and burst into the box, but his left-foot shot rebounded off the crossbar. Posh levelled through Chris CONN-CLARKE who superbly found the back of the net from distance after a poor clearance from the Foxes goalkeeper.
Parity didn't last long though as PAGE swept home his second of the game from close-range after a cross from the right.
Leicester added a superb third two minutes from time with Silko THOMAS finding the top corner with an outstanding left-foot strike from distance.
Posh are next in action on Tuesday evening with a trip to Stamford.
