Pompey currently boast the best defence and the only unbeaten record in League One.
And neither of those impressive statistics were ended by a goalless draw with Cambridge at the Abbey Stadium.
Regan Poole was pleased that the seemingly impregnable Blues were able to add another clean sheet.
But there was a feeling of frustration that they could not find the net at the other end of the pitch to turn one point into three.
The centre-back said: “We’re disappointed because we’d been on a great run going into the game, but it’s certainly not the worst point in the world.
“I thought we were by far the better side and deserved the win, although weren’t able to create a lot in the second half.
“There were a lot of chances before the break that we couldn’t take and just needed to be more ruthless to put the game to bed.
"We’re delighted to keep another clean sheet – which is our job done at the back. That’s a real positive, with everyone chipping in."
“It was a great block to deny Colby and Abu hit the post as well, while there were a couple of penalty shouts, but it wasn’t quite our day.
“We’re delighted to keep another clean sheet – which is our job done at the back. That’s a real positive, with everyone chipping in.
“The full-backs have changed, but it doesn’t matter who plays because we know what we’re getting from each of them and what they bring to the side.
“Our defensive record is up there with the best, so we’re pleased with that, but just gutted not to come away with the three points.”
Poole recently made his senior international debut for Wales in their comfortable friendly victory over Gibraltar.
He said: “It was something I’ve been wanting to do and now I’ve got in there, I really want to stay there.
“Hopefully my club form can do that, but if not, then I can always say that I’ve played for Wales. I’m happy that my family got to see that.
“It was a while since my last call-up, so you do start to lose a bit of faith. Now I want to be in every camp and part of a good squad.”
