Steve Cotterill toasted another sensational Pompey away triumph after watching his side inflict a 1-0 defeat on Leicester.
David Nugent’s 14th-minute strike was enough to clinch victory at the Walkers Stadium on Saturday.
The Foxes were booed off after being outplayed by Cotterill’s men in a match they had expected to celebrate victory.
For Pompey, it was another notable scalp on the road following impressive wins at Norwich, Swansea and Ipswich since December.
Their latest victory keeps them within six points of the play-offs and one point off Sven-Goran Eriksson’s ambitious side.
Pompey boss Cotterill admitted it was another away display to savour as his side keeps marching on.
He said: ‘We’ve had some great away wins this year, some real tough ones.
‘We are thankful we’ve got another one. We enjoyed that on Saturday.
‘We’ve won at Norwich, we’ve won at Swansea, we’ve won at Ipswich and now at Leicester.
‘We have had some good away wins.
‘Don’t forget we have had some good results at home as well.
‘It just helps us when we have a good surface to play on.
‘At the moment Fratton has gone a bit bobbly, that is a bit of a problem for us sometimes.
‘Leicester was a very hard-fought victory. We felt – up to the goal – we gave as good as we got.
‘I actually felt we started the game brighter than they did.
‘After the goal we took a bit of a backward step and for the last 15 minutes of the first half we needed to defend well.
‘We also needed to defend well all of the second half, bar a few counter-attacks. Having said that, we won the game 1-0 and it could have been two if Joel Ward had put that chance in at the death.
‘He’s actually waited for the ball to come to him rather than meeting the ball and stabbing it into the net.
‘But we were delighted with our effort, application and our football at times.
‘The players did everything asked of them and I mean to the letter of the law.
‘They didn’t step out of line once.’
While Nugent proved to be the match-winner, Jamie Ashdown also caught the eye.
He produced a stunning stop from Sol Bamba’s first-half header before racing off his line to block Paul Gallagher in the second half.
And both players drew praise from their manager.
Cotterill added: ‘It was a great goal from Nuge, you just want it to drop to him.
‘I didn’t want it to drop to any of our defenders to kick it into the crowd.
‘I needed it to drop to either a Nugent or a Kitson, who are technically good players.
‘Thankfully it did.
‘As for Jamie, there were two great saves he made. The other stuff I thought was routine but he made two good saves.
‘It has been an absolute desperate situation at Portsmouth and for those lads to go and give a performance like that and the amount of fans we get is a credit to this football club.’
