Crystal Palace manager Dougie Freedman reckons Kagisho Dikgacoi's brush with Brazil has rubbed off on the midfielder after his classy strike sank Charlton 1-0.

Dikgacoi played in South Africa's friendly defeat in Sao Paulo at the weekend, and then settled the south London derby as Palace won in the league at The Valley for the first time since 1968. The former Fulham star latched on to Damien Delaney's knock down and lashed a fine volley past Addicks keeper Ben Hamer six minutes into the second half.

"It was a fantastic goal," said Eagles boss Freedman. "He was playing against Brazil at the weekend and he said he'd picked up a few tips, it was a great strike."

Newly promoted Charlton can feel hard done by, though, not least when Bradley Wright-Phillips had what looked a perfectly good goal ruled out after half an hour. Palace defender Darcy Blake was playing the striker onside after slipping to the floor as his header flew into the net, but a linesman's flag curtailed the celebrations.

Charlton had plenty of other chances and in stoppage time substitute Ricardo Fuller's shot was deflected on to the crossbar. And from the corner Owen Garvan denied the hosts an equaliser when he cleared a header from home keeper Hamer off the line.

It meant Palace secured back-to-back wins - a far cry from three defeats in their first three matches - but Freedman admitted luck was on their side for a change. "Sometimes they go for you, sometimes they don't," he said.

"Darcy slipped over to make it onside but you are talking inches. We rode our luck but we were in a derby match and sometimes you have to."

Addicks boss Chris Powell revealed the assistant referee apologised to him afterwards for the offside decision. "It wasn't to be for us tonight," he said.

"Palace started well, but we grew into the game and the turning point was a disallowed goal that should have stood. We had a couple cleared off the line as well. Palace had their chances and it was a well-taken goal, but it just didn't happen for us.

"To be fair to the assistant he came into my room and apologised. It doesn't do us much good though."
