He scored the goal that sent Pompey into the second round of the Emirates FA Cup.
But Marcus Harness conceded that the overall display against non-league Harrow Borough could have been better.
The forward capped an impressive individual performance by slotting home Mahlon Romeo’s pass to take his tally for the season to six.
And he is pleased to have helped the Blues progress, despite a patchy showing from the side after the break.
Harness said: “We started the game well, created a lot of chances and could have been four or five goals ahead.
“We then lost our control midway through the second half, although we’re happy to be through to the next round.
"We were looking to build from there and score some goals, but unfortunately it didn’t work out that way."
“It was quite a professional job from us and we weren’t ever in any real danger, even if it wasn’t always pretty.
“Mahlon found me with the pull-back and that’s where I want them, rather than in the air and on my head.
“We were looking to build from there and score some goals, but unfortunately it didn’t work out that way.
“You want to be on it 100 per cent for 90 minutes and we just have to keep trying to get as close to perfect as we can.
“The manager wasn’t very happy with the overall performance, so they’ll dissect the game and we’ll take some learning from it.”
Pompey will learn their second round opponents when the draw for the second round is conducted on Monday evening.
Harness said: “There are still some big clubs at this stage of the competition, so we’ll be looking forward to see who we get.”
