Sydney are bottom of the table and yet to notch up their first win after four games with just two draws to their credit.

Yesterday the club said the board had not even discussed replacing Culina, but he admits he’s under pressure to produce results for Sydney soon.

But he rejected being to blame for the side’s dismal start to the season and said losing players like Alvin Ceccoli, Sasho Petrovski and David Carney had set the club’s back.

“I challenge anyone to lose that type of quality and still get everything spot on straight away," he told the Sydney Morning Herald.

“I've done nothing different now to what I did when everyone was saying how good we were playing in the Asian Champions League.”

He claims he’s coming under increased pressure despite Victory and Adelaide not winning yet either but coaches Ernie Merrick and Aurelio Vidmar were escaping the same media scrutiny.

However Melbourne are so far unbeaten, and United have just lost once compared to Sydney’s double defeats this season.

Culina added: "We're a good team and we'll bounce back, but because it's Sydney, everyone talks about it more.

“That's the thing about Sydney – everyone likes to have a go at them.”

Culina has also bemoaned the lack of quality strikers in the A-League, saying the competition needs finishers capable of scoring 15 or 16 goals a season.

He even took a swipe at Melbourne Victory’s Archie Thompson and Danny Allsopp for under-performing despite scoring 27 goals between them last season, including Thompson’s five in the grand final.

"It's fair to say the competition lacks really creative and good finishers," Culina told AAP.

"No disrespect to the teams, including mine, but tell me one player in the two years gone that has really sort of made an impact in front of goals.

"We talk about Allsopp last year, saying he had a great year - but he still only scored 11 goals in the normal season in 21 games. Is that very good? I don't know.

"I mean it was good enough for Melbourne because Archie scored 10 as well, but when you look at it, I don't think any team has had a prolific goal scorer.

"Archie and Allsopp last year were the leading strikers, how many goals have they scored this year?"

He added: "I'm not quite sure that I see enough really good finishers in any of the teams to score the 15, 16 goals that I think a quality striker should in 21 games.

"It's a problem for the competition and I think what we need to do is take a few extra risks.

"There's all this pressure to get goals, sometimes the emphasis is more on the result rather than the way you play the game and I think teams will go out and say, `I'd rather get a 1-0 win than a 4-all draw."
