Ronan Curtis is confident that Pompey have what it takes to secure a League One play-off spot this season.
He scored the only goal of the game against Bristol Rovers at a sunny Fratton Park to end a four-match winless run.
The result – which relegated the visitors – means it is only goal difference keeping the Blues out of the top six.
And with just three fixtures remaining, Curtis has urged them to keep battling away in order to extend the campaign.
He said: “We can do amazing things with this group of players and hopefully this is the start of another run to the end of the season.
“There are three games left and each one is now like a cup final for us as we try to get into those play-offs.
“It feels good to win, but we’ve got to take it step by step and look to keep on getting more results like that.
"We can do amazing things with this group of players and hopefully this is the start of another run."
“We need to give everything in each game and hopefully we’re in the top six after the last one of them.
“I’ve got trust in this group of lads and everyone – including all the staff and the board – here is excellent, so hopefully we can get the job done.
“We’ll go to Accrington on Tuesday night and it might not be pretty, but we’re there to try to win again.
“There are a lot of injuries at the moment – especially in attacking positions – and there’s plenty of talent missing.
“Those front four are having to play almost every minute and it’s mentally tough, but I want to play in all the games because I love it.”
Curtis bent a fine finish into the bottom corner midway through the first half after receiving an inventive pass from George Byers.
He said: “We’ve been working hard in training and we see that he’s got the ability to do things like that.
“I knew what he was capable of, so we played the one-two and then I was pleased to see the ball go into the net.”
