But they wasted several scoring chances and many promising attacking positions before substitute Jonson Clarke-Harris came on to show his teammates how to do it.
One Posh player in particular continued his good recent form, but a couple of the back up boys did themselves few favours in the 1-1 draw, a result good enough to take Grant McCann’s men through to the second round of the EFL Trophy.

1. LUCAS BERGSTROM
No chance with the Wycombe goal after being a spectator for most of the first hour. Saved one penalty in the shootout. 6 Photo: Joe Dent
2. JOE WARD
Excellent first-half from the right-back position when he won many tackles and delivered several good crosses. Teed up Joe Randall for a sitter after the break as well. Seems to be better coming from deeper positions 8. Photo: Joe Dent
3. RONNIE EDWARDS
An immaculate passing display from the back including one wonderful long ball to Ward which should have led to a first-half goal. Occasionally roughed up, but a decent return to the side apart from a skied penalty in the shootout 7. Photo: Joe Dent
4. KELL WATTS
The debutant can certainly see a pass out from the back and his left-footedness added some much needed balance to the defence. A set-piece threat also, apart from seeing his penalty saved in the post-match nonsense. Encouraging overall 7. Photo: Joe Dent
