He made an explosive start to his Pompey career after signing from Burton over the summer.
But a thigh injury halted Marcus Harness’ progress and he has had to contend with cameo roles in recent weeks.
The midfielder was back in the starting line-up for the Blues’ FA Cup victory over Altrincham at the weekend, however.
And after playing a key role in both of the home side’s goals, he is looking to play a prominent part in upcoming fixtures.
Harness said: “I was buzzing to be back in the starting line-up and hopefully I can play a bit more to help the team continue our form.
“The aim is to make the position my own, but Ronan Curtis and Ryan Williams are both really good players.
"I was buzzing to be back in the starting line-up and hopefully I can play a bit more to help the team continue our form."
“We’ve just got to keep pushing each other to perform at our best and I think the team can benefit from that competition.
“It can be tough when you come back for the first time, but the body feels good and it will be interesting to see the stats on Monday morning.”
Pompey needed a stoppage-time header from Brett Pitman to see off their National League North opponents and reach the third round.
Harness said: “We had to grind the result out and sometimes you just have to take the win, however it comes about.
“It’s the sign of a good team that you can not play particularly well, but still get a positive result and we’re moving in the right direction.
“I’m open to anything in the next round, although I’ve done Manchester City before with Burton and it wasn’t fun!”
