Pompey dominated possession against Charlton and spent most of Fratton contest camped out in the visitors’ half.
But the statistic of one shot on target shows where they went wrong on a windy day on the south coast.
The Addicks certainly deserve praise for their defensive display, while Jonny Williams and Chuks Aneke scored to secure them the points.
And Kenny Jackett wanted to see his side to do more to test Ben Amos, who had a largely comfortable afternoon between the sticks.
The Blues boss said: “We put a lot of pressure on Charlton and had the vast majority of the game, but just couldn’t find those moments in and around the box.
“They defended extremely well and when we got into the final third, it was difficult for us to get the shots off.
“It was wave after wave of blue throughout the contest and we tried a number of different set-ups as well.
"We looked in control after the break, but for all the good approach work, we couldn’t test their goalkeeper."
“Despite all that pressure, though, we didn’t really have many of those clear-cut chances that you’re looking for.
“Both sides have had one decent opportunity in the first half – with Ronan Curtis’ coming in the opening few minutes – but they’ve scored and we haven’t.
“We looked in control after the break, but for all the good approach work, we couldn’t test their goalkeeper.
“There were too many crosses close to him and the quality of our set-pieces wasn’t quite there on this occasion.”
There was concern when Jack Whatmough failed to emerge for the start of the second half, with Rasmus Nicolaisen coming on in his place.
Jackett explained: “Jack felt the top part of his left hamstring. It’s not too bad, although he’s certainly going to miss the game on Tuesday.
“It’s not his knee, which is always good news. He’s started the season well, but Rasmus has impressed in training and I’m confident in his ability.”
