It was a comfortable victory that took Pompey to within a point of League One’s automatic promotion places.
But Kenny Jackett is still looking for more from his side following their 2-0 defeat of Swindon at a freezing Fratton Park.
An early goal from Ronan Curtis failed to open the floodgates, with Ellis Harrison wrapping things up from the penalty spot after the break.
Now Jackett wants to see his side convert more of their chances to put opposition teams to the sword.
The Blues boss said: “We’re delighted with the win and were on top during the game, but would have loved even more goals.
“We found that edge earlier in the season and were able to put sides away, although couldn’t quite do it on this occasion.
"We just have to work on different ways of going forward to score those goals and make the most of the openings we create."
“It was a good clean sheet and I don’t think Swindon created too much, with my goalkeeper not having too much to do.
“The combination of the two centre-halves, as well as Tom Naylor in front of them, really helped us in that respect.
“Now we just have to work on different ways of going forward to score those goals and make the most of the openings we create.
“There was some fresh energy coming into the side – and that’s a big thing as you search for those explosive moments.
“George Byers came on and made a difference because I don’t think we started the second half particularly well.
“I thought we were in control, but unless the scoreline really gets away, then you don’t necessarily feel comfortable.”
