Connor Ogilvie was signed by Pompey over the summer to battle it out with Lee Brown for the left-back berth.
A series of injuries, however, mean he has mostly been utilised as a central defender so far this season.
But the 25-year-old has played a pivotal role in a Pompey side that are unbeaten in nine matches and have conceded just once in their last six outings.
And with the Blues now just a couple of points outside the League One play-off spots, Ogilvie is keen to ensure that continues.
He said: “I just enjoy playing football, so as long as I’m out on the pitch, then I’ll always put my all into it.
“You’ve got to deal with circumstances – adapt and overcome. I will keep trying to do my best for the team.
“It’s a collective and the 11 guys out on the pitch have to fight for each other, as we have been doing recently.
“Hopefully we can extend this run we’re on because we want to keep winning games and keep climbing the table.
"You’ve got to deal with circumstances – adapt and overcome. I will keep trying to do my best for the team."
“There were a lot of new faces and relationships over the summer and everything seems to be clicking now.
“Pompey are a massive club and we need to be up there, so we’ll continue working as hard as we possibly can.”
A stoppage-time strike ensured that the Blues won 1-0 at Ogilvie’s former club Gillingham at the weekend.
He said: “It was a tough game – especially with the weather conditions – and we had to grind things out and keep going until the very end.
“There were strong winds and that made it difficult, while John Akinde is a big boy who causes problems.
“Kieron Freeman and I normally play as full-backs, while Shaun Williams is usually in the centre of midfield.
“So we had to remain resolute and make sure that the back three stayed together, but I thought we did exactly that.
“It was nice to see a lot of familiar faces on Saturday and I wish them all the best for the rest of the season.”
