HAVING upstaged Harry Kewell, Adelaide United playmaker Dario Vidosic is now targeting Brett Emerton's struggling Sydney FC.

At 24, with Bundesliga experience and 14 Socceroo caps, Vidosic is arguably the competition's most discerning marquee addition with Kewell's Victory and Emerton's Sydney Sky Blues so far winless and scoreless this season.

"Our understanding is only going to get better and better. I think we will see an even better performance against Sydney FC," predicted Vidosic, who cut up Victory in his Friday night Reds debut at Hindmarsh following a prolonged four-year stint with Bundesliga side FC Nuremberg.

"Hopefully we can knock off Sydney and then Brisbane who could have a 31-game unbeaten streak by round four."

Sydney FC coach Vitezslav Lavicka will ponder a switch for wing jewel Emerton to a central creative role but Vidosic says it will matter little where the former Blackburn Rovers favourite starts on Saturday at Hindmarsh.

"Sydney FC is a good team and we know we need to play with the same intensity as we did against Melbourne Victory to win," said Vidosic, who had been dogged by sickness, knee and hamstring strains since joining the Reds in July.

"We have to prepare for everything and not just worry about one player. Emerton is a quality player, dangerous but we need to worry about them all because the others can punish us."

While Flores was a big loss, new No. 10 Vidosic warmed hearts at Hindmarsh during the 1-0- defeat of Victory.

"I heard a lot about Marcos from last season but he has his style and I have mine," said Vidosic providing the missing link in an Adelaide unit that was rudderless and impotent in the season-opening loss to Perth Glory.

"I thought I could have done a few things better but felt good in that I could last the full 90 minutes.

"It was nice to start in front of 15,000 fans, a massive derby."

Vidosic revealed he revved up the Reds during the break on Friday night believing Victory was exposed in midfield and employing a predictable route to lone striker Kewell.

"I told the boys we had Melbourne on the ropes, they looked lost and we just needed to go for everything and the crowd helped as well," said Vidosic, with golden boot Serginho van Dijk scoring the vital 52nd minute winner.
