Leyton Orient assistant manager Kevin Nugent felt his side should have won at Peterborough.
Alex Revell cancelled out Aaron Mclean's opener from the penalty spot after Jason Brown was adjudged to have felled George Boyd, and Jimmy Smith`s late equaliser salvaged a 2-2 draw.
"We created seven or eight what I would call excellent scoring chances, and for that fact alone we have to be disappointed not to have won the game," said Nugent. "We are also feeling a bit aggrieved about the award of their first penalty because it didn't look like a spot-kick whatsoever.
"But on the other hand we came from behind twice and that highlights the character and strength within a group that is suffering from a fair few injuries. We have spent most of our time lately patching the players up and have had hardly any time to actually get any work done on systems.
"I'm definitely looking forward to having the chance to watch our second goal again on the video because it was a great strike from Jimmy Smith after some excellent football.
"We probably can't argue too much about the second Peterborough penalty because there was a rash challenge - but I also felt we should have a penalty ourselves."
