Perry Northeast is expecting his players to show their true quality when they play Sheffield for the second time this season on Sunday.
The Blues were beaten 2-0 in the previous clash between the sides in the league cup in March.
But this is a far bigger game, with the prize of promotion to the FA Super League on offer to the winners of the contest at Stratford Town (2pm).
Sealing the FA Premier League southern division title just over a week ago will have given Northeast’s side plenty of confidence.
The players clearly believe they are lining up for a club fit for the Super League.
Now they have the chance to show it with victory on the field in the play-off game between the southern division champions and the title winners from the northern division.
Pompey boss Northeast is confident his players will deliver their best form.
He knows they have more to give from the previous time the sides met.
‘We are all happy to be there,’ he said.
‘The players have worked so hard to get this far.
‘Hopefully we will carry on our form from the rest of the season.
‘We played Sheffield earlier in the season and have more of a game plan because we know a bit more about them.
‘Potentially the trick up our sleeve is we didn’t perform to our capabilities on that day.
‘We could have done more on that occasion.
‘It was a tight game and we took the positives out of it.
‘We came off the pitch knowing if we had given that extra five, or 10 per cent, it could have been different.
‘The match was a long time ago now and there will be no psychological advantage from it.
‘We have enough experience in our squad to deal with the magnitude of the game.
‘Our players have performed in nervous and tough situations this season.
‘We went away to Brighton and won 2-0 in the league and went away to Cardiff and kept a clean sheet.’
Winning the title at Privett Park with the 3-1 win against West Ham was a big achievement for the team.
They rightly celebrated in style but have quickly turned their attentions to Sunday.
And whatever the outcome in the play-off match, when the season is finished on Sunday evening, Northeast will allow himself a drink to toast a very progressive campaign.
He added: ‘It will be a great day and whatever happens I am going to have a beer afterwards because it’s bank holiday the next day.
‘We know it will be an excellent atmosphere and our fans could make it like a home game for us.’
‘They will create a buzz around the ground and even if we just take around 50 we know they will sound like 500.’
