He scored the late penalty that ensured the Blues continued their unbeaten league record by drawing with Shrewsbury.
But Brett Pitman felt he should have had another opportunity to score from the spot at Fratton Park.
The substitute converted after Nathan Thompson had been brought down by Alex Gilliead with just three minutes of normal time remaining.
However, Pompey’s skipper also felt he had been manhandled by defender Josh Emmanuel moments earlier.
Pitman said: “It was one of those that in the middle of the pitch you would get all the time.
“Defenders always get away with holding on to you and not making any attempt to go for the ball – literally pinning you so you can’t move.
"If you strike it well and it goes into the corner then it should go in, even if the keeper goes the right way."
“The linesman gave the second one. I couldn’t see whether it was or wasn’t, but the lads in the dressing room said it was.
“I think it made it more difficult that I’d taken one in midweek because they watch videos and know where you put it.
“You’ve just got to pick your spot and make sure you hit it properly. I always practice on a Friday and know where I’m going to go.
“If you strike it well and it goes into the corner then it should go in, even if the keeper goes the right way. If it doesn’t then you say fair play for saving it.”
Pompey were lacking the vibrancy that has been evident in recent weeks and had to respond to Greg Docherty’s opener.
Pitman said: “You look at the league table and think perhaps it won’t be tough – but we knew that wouldn’t be the case.
“Shrewsbury were better than the position they’re in suggests and had a high turnover of players after an excellent last season.
“We probably didn’t hit the heights we expect and you have to give credit to our opponents for that because they were very good.
“Obviously we wanted three points, but when you’re 1-0 down so late on, then obviously you’ll take the one.”
