Portsmouth boss Harry Redknapp has challenged David Nugent to prove he is worth a permanent starting place at Fratton Park, after he fired Pompey into the Carling Cup fourth round.
Nugent's 69th-minute effort last night nudged the Barclays Premier League side past Burnley - and was only his second goal since moving south in a 6million summer move.
Redknapp famously spoke of selling Nugent within weeks of landing him on a four-year contract - but now he believes he is capable of building on his goal at Turf Moor.
Redknapp said: "I hope David will come on from this. He needs to work hard and take his chances when they come. We've got a bit of competition up there - because Kanu has been fantastic, and I have got four up front.''
The Pompey manager may have thought differently had Nugent not managed to atone for his 18th-minute howler when he ought to have given the visitors an early advantage.
Nugent sprang the offside trap to race on to Pedro Mendes' through-ball but was caught out trying to nutmeg the upright Gabor Kiraly instead of shooting for what would have been a certain goal.
Moments later, a similar ball gave Nugent the chance to go clear on the goalkeeper again - but hesitation by the striker allowed Steve Jordan to get back with a superb sliding challenge in the box.
While Pompey were in control at the start, Burnley responded well with the excellent Alan Mahon at the centre of most of their moves and Ade Akinbiyi lively up front.
Clarets boss Steve Cotterill said: "I'm delighted with the performance tonight. The boys who came in did very well, and I think they can be very proud of themselves against a very good team.''
Burnley had their best chance in the 33rd minute when Mahon sent in a fine corner from the right - and Steven Caldwell rose at the far post, only to see his point-blank header blocked by Jamie Ashdown.
Four minutes before the break, Akinbiyi missed another chance to put the Clarets in front when he rose highest to meet a Mahon corner but steered his header straight at the Pompey goalkeeper.
Redknapp had made 10 changes from the side which won down the road at Blackburn 48 hours earlier - but his new-look line-up gelled well and continued to hold the upper hand in the second half.
Nugent raced on to a lofted through-ball from Mendes - and while Burnley furiously protested that he had handled the ball to get it under control, he coolly slid the winner past Kiraly.
Redknapp added: "We were okay in the first half and in the second half we kept the ball quite comfortably. It's always difficult when you make 10 changes and put another team out.
"We've had a good week. We came up here for two tough games and we won them both. If we get a good result on Saturday it will have been a fantastic start to the season for us.''
