Connor Ogilvie hailed a battling Pompey performance at MK Dons that arguably warranted more than a point.
They had play more than half the contest with just 10 men following a controversial red card for Joe Morrell.
That came after Ogilvie had given the visitors an early advantage that was cancelled out by Mo Eisa in the second half.
And the defender felt that the Blues did well to limit their opponents, despite their numerical disadvantage.
He said: “Going down to 10 men is never ideal and the boys have had to work so hard – we dug in really deep.
“I didn’t see what happened with the sending off at all and the first I knew anything had happened was when the referee pulled out the red card.
“It was really confusing and nobody else has seen anything. It was disappointing because we had a good foothold and were dominating.
"We’re frustrated to come away with just the single point because I thought we played well enough to get all three."
“We were then on the back foot, but we managed to limit MK Dons to almost nothing in terms of chances.
“We’re frustrated to come away with just the single point because I thought we played well enough to get all three.
“I was right behind Joe Pigott’s shot at the very end and was waiting for the net to bulge, but unfortunately it hit the crossbar.
“But we’ll be ready to go again on Monday and try to get the victory against Morecambe at Fratton Park.”
Ogilvie made it five goals for the season with a neat volleyed finish to convert Sean Raggett’s cross from the right.
He said: “It was a great ball in from Raggs and I just fancied getting in at the back post – thankfully it’s ended up in the net.
“I was just thinking that I had to get the ball on target and that ensured we got off to a really good start.”
