Danny East lauded Andy Awford for restoring the fun factor at Fratton Park.
And the Pompey defender believes a repeat of this season’s finale will make his side an unstoppable force in the new campaign.
East came into the first-team picture at the end of the season with starts in the final three games, after being sidelined since December with an ankle injury.
The 22-year-old impressed as his team finished with five wins and two draws.
That run saw Awford named League Two’s manager of the month for April as he was given the job on a permanent basis.
East felt that had to be the case with the impact he made.
And the former Hull man reckons a repeat of the level of displays his side produced next season will make them a hard team to stop.
East said: ‘If we took the form we had at the end of the season, could anyone see us being stopped? We’d be unstoppable.
‘Awfs is a great motivator. He’s very professional in what he does. He speaks very well and he gets the lads together.
‘He’s a top man. It’s a fun place to be now.
‘We were getting three points virtually every game at the end of the season.
‘So he deserved to get the job.’
East is confident Pompey fans will be back to see their team’s assault on League Two next season.
There were 10,670 season tickets sold last summer and the player feels there is still optimism among fans.
He said: ‘If they’ve seen what we’re doing now under Awfs, with the team and the squad together, surely they will be thinking about coming back.
‘Seeing their faces when I scored at Northampton, you can see how much they love it.
‘I’m sure they are going to come back.’
