It was a result that saw Pompey stretch their unbeaten run in League One to three matches.
But Danny Cowley is looking for more quality from his troops following a 1-1 draw with Cheltenham at Fratton Park.
Both goals were scored in the first half, with Reeco Hackett cancelling out Lewis Freestone’s opener for the Robins.
There were chances for the home side to make it back-to-back victories and Cowley was disappointed they could not find another breakthrough.
The Blues boss said: “We knew that Cheltenham were a threat from throw-ins, but we didn’t react well enough and conceded a really soft goal.
“When you’re playing against such a resolute side and they go ahead, they move to a back five and make it very difficult for you.
“But we responded – it took us a little bit of time, but we did. We scored the equaliser and then just lacked a bit of quality in the second half.
“That’s ultimately why we didn’t win the game. There were maybe three clear-cut chances and we need to take them.
"This was a game we desperately wanted to win and if I’m being totally honest, I just want better for us."
“There’s a positive that we created them and I certainly couldn’t fault the intensity or the commitment of the players.
“But this was a game we desperately wanted to win and if I’m being totally honest, I just want better for us.”
Louis Thompson was handed his first league start for the club alongside Joe Morrell in the centre of midfield.
Cowley said: “He grew into the game and has certainly got power, providing us with some dynamism in the middle of the pitch.
“We’re just trying to build up his fitness because he’s probably only ready for 60 minutes in a league game at the moment.
“We’ll keep working with him on that, but Louis showed glimpses of the player that we know he can be.”
Cowley also revealed that a hamstring problem suffered by Ryan Tunnicliffe on Saturday is more serious than initially thought.
He said: “We didn’t think it was a bad one, but the scan has shown a much nastier injury, so that’s a real disappointment for us. Now he’ll have to see a specialist.”
