Gareth Evans is a prime candidate to talk about the differences between the fourth and third tiers of English football.
He was a key member of the Pompey side that memorably clinched the League Two title on the final day of last season.
The versatile right-sided player has found appearances a bit harder to come by at a higher level this term.
But a return to the side in recent weeks coincided with an upturn in form and Evans is feeling confident.
He said: “I’ve played the past three games and we’ve got three wins, so things are looking up for me personally and also for the team.
“I think we had a bit of bad luck with some of our results recently – especially the Bradford home game.
"We perhaps got away with the odd mistake last season, but you tend to get punished for them a bit more in League One."
“But we’ve managed to turn things around in a really strong division that is definitely a step up from League Two.
“The players seem to be a bit quicker and stronger – there’s a lot more talent out there, so we need to adjust to that, although it’s nothing we can’t cope with.
“We perhaps got away with the odd mistake last season, but you tend to get punished for them a bit more in League One.”
Pompey sit just two points outside the top six ahead of this evening’s trip to 11th-placed Peterborough.
Evans said: “It’s never easy when you’ve got Saturday, Tuesday, Saturday, but I believe we’ve got a squad strong enough to deal with it.
“We want to be in the play-offs and that’s the aim, so we need to keep winning games and work our way into those positions.”
