Dindane made amends for his first-half penalty miss with an 84th-minute goal
By Pranav Soneji
Avram Grant earned his first victory as Portsmouth ended a fractious week off the pitch with victory against Burnley.
Pompey - whose players were only paid their latest wages after a loan - took the lead when Hermann Hreidarsson fired home a left-footed shot on 65 minutes.
Burnley were frustrated by Asmir Begovic, who made fine saves to deny Kevin McDonald and Steven Fletcher.
And Aruna Didane, who had a first-half penalty saved by Brian Jensen, secured the victory with an 84th-minute header.
The victory - Pompey's third in the league this season - will lift the spirits of the beleaguered club following a destabilising week off the pitch.

But the south-coast club were dominated by Burnley in the first hour and only had the heroics of Bosnian keeper Begovic to keep the scoreline level in the first hour.
The away defeat is Burnley's seventh of the Premier League campaign, a fact which will concern manager Owen Coyle, despite the visitors' enterprising attacking play.
Grant made two changes from the side that lost to Manchester United, with Tommy Smith recalled up front while Steve Finnan slotted in at right-back in place of the suspended Younes Kaboul.
Burnley made just one alteration with McDonald replacing suspended skipper Steve Caldwell.
And the visitors made the most of the opening exchanges, pressing Portsmouth's midfield and giving them little opportunity to construct a fluid passing game.
Midfielder Wade Elliott was at the heart of Burnley's best moves, creating an excellent chance following a strong right-wing run in the 18th minute, but striker Fletcher's weak 10-yard strike was gathered easily by Begovic.
With the visitors beginning to dictate the tempo of the match, Portsmouth were awarded a fortuitous penalty in the 31st minute when Elliott was adjudged to have brought down Hreidarsson inside the box.
Burnley's players were furious - and TV replays justified their grievances as Elliott's foot was nowhere near Hreidarsson - but Dindane's feeble spot-kick miss made amends for a poor decision by Phil Dowd, with keeper Jensen saving the Ivorian's follow-up header.
Grant fumed on the sidelines, his fury further compounded by Dindane's decision to take the penalty with regular penalty taker and top scorer Boateng on the pitch.
Dindane attempted to compensate for his earlier miss, but, after beating Andre Bikey with a powerful 42nd-minute right-wing surge, fired his byline cross at Jensen with Boateng waiting unmarked inside the six-yard box.
With little to cheer in the first 45 minutes, the fraught nerves of the home fans were further tested as Burnley dominated the start of the second half.
Begovic tipped over a powerful 25-yard drive from McDonald in the 52nd minute while Steven Fletcher fired a left-footed strike just wide of the far post seconds later.
The keeper once again denied Burnley, this time with a brilliant one-handed diving save from Fletcher's excellent left-footed volley from outside the box in the 62nd minute.

With his side close to capitulation, Grant brought on the experience of Kanu for the ineffectual Smith - and he made an immediate impact as Portsmouth took an undeserved lead.
The Nigerian played a neat one-two on the edge of the area with Hreidarsson, who strode into the penalty area and struck a clinical left-footed strike across Jensen's goal.
Kanu was once again the creator as he fed a pinpoint pass for Boateng in the 70th minute, but the former Spurs midfielder fired his shot into the side netting from the edge of the six-yard box.
With Burnley's resolve gradually fading, Portsmouth sealed the victory with six minutes to spare when Dindane made amends for his earlier spot-kick miss.
The striker rose unchallenged to head in Jamie O'Hara's left-footed cross from inside the six-yard box.
Hermann Hreidarsson on his role in Portsmouth's first-half penalty: "It wasn't a penalty. I was waiting for the kick but it never came. It wasn't a dive, it's not what I'm about, but it wasn't a penalty.
"This was a massive win for us and hopefully it's a the start of something special.
"Hopefully we'll kick on from here. There's loads of points to be played for still."
Burnley boss Owen Coyle: "We performed well but not left with any points. Our level of performance was of a high standard, our passing and moving resulted in numerous chances but we really had to get ourselves in front.
"However, we conceded two soft goals.
"The margins are minimal. We had enough chances; a little bit of quality finishing from us and we'd have seen the game off."
