Successive defeats to Blackpool and Oxford have halted Pompey’s momentum.
But Lee Brown has called for calm heads to ensure that the Blues quickly get their form back on track.
The Blues were beaten 2-1 in their most recent outing at the Kassam Stadium, despite Brett Pitman’s spectacular strike.
They are still currently sitting at the League One summit, however, and Brown wants to see a bit of perspective.
The left-back said: “Is it a crisis? No. It might feel like it now, but you have to take a step back and look at the bigger picture.
“We’ve won some very tight games this season and this just happens to be one of those times when we haven’t.
"Is it a crisis? No. It might feel like it now, but you have to take a step back and look at the bigger picture."
“It’s hard to put your finger on why you lose and you can over-analyse things. You’re going to get these matches.
“We don’t need to change too much because then you go away from what we’ve done so well in the first half of the season.
“Of course the boys are hurting and it’s frustrating, but that’s the first time this season we’ve lost back-to-back games.
“Even at the end I thought we might be able to get something after we scored, but unfortunately it wasn’t to be.
“We’ve done well to give ourselves a cushion, which meant we could lose a couple and still be top of the league.
“We’ll stay together and keep working – the fans know that this group of players aren’t going to roll over.”
Brown made his first appearance of 2019 against Oxford, coming straight back into the team after recovering from a hamstring injury.
He said: “It was nice to be out there again. You do miss it when you’re out, especially when you’ve found a bit of rhythm.”
