Ryan Williams has warned Pompey’s League One rivals that they still have plenty of room for improvement.
The Australia international has helped the Blues secure a club record nine successive victories in all competitions.
That has seen them climb into the League One play-off spots, as well as secure FA Cup and Leasing.com Trophy progress.
But Williams believes they can perform better ahead of a trip to face a Coventry side also battling for promotion.
The winger said: “We’ll be in for a good points total if we can catch up on our games in hand and can hopefully have a successful season.
“We’re hitting form at the right time and aren’t playing unbelievably well, but we’re still winning matches and are feeling confident.
“Now you want that gap to start appearing between sixth and seventh and then to push on from there.
"We’re hitting form at the right time and aren’t playing unbelievably well, but we’re still winning matches."
“I still feel like there’s a lot more to come from us this season and we’re perhaps due a bit more luck, something we haven’t really had a lot of.
“We’re in a bit of a false position at the moment because of the number of games we’ve got in hand, so it’s good they’re coming along sooner rather than later.
“I can’t think of a time when I’ve ever won nine in a row before, so now we want to make it 10 – and why not?
“Coventry are a really good team, but it should be an interesting match between two sides who are in decent form.”
Williams found the net in Saturday’s 2-0 victory at Tranmere to double his personal tally for the season.
He said: “I want more goals and I’ve had quite a few chances in recent weeks where I’ve gone pretty close.
“I’m just trying to get back into things and gain some more confidence after having that little injury, so hopefully there are more to come.”
