The harbour side team will be looking to progress to the semi-finals of national knock-out competition for the first time in their history when they travel to Sydney's west to take on the NPL underdogs.

While a win for Blacktown would provide another ‘Magic of the Cup’ moment, Zullo doesn’t mind being cast as the villain as the Sky Blues seek to end City’s charmed cup run.

“I think fairy tales and stuff like that are always nice,” Zullo said. “But as players it doesn’t have the same effect on us because we go out there to win every single game.

“We want to win just as much as anyone else and I think a lot of the players have been at Sydney FC for a while and haven’t been lucky enough to win silverware. 

“Essentially three wins from this point and you have a trophy so that is not far between here and winning the tournament and we are wanting to be pretty merciless and do our thing.”

Zullo’s direct opponent during the clash could be City winger Danny Choi, but while the Sky Blue defender is aware of the 23-year-old's ability, he doesn't see him as a threat.

“Fair play to him, he’s played well in the games,” he said. “But it doesn’t really matter who I’m playing against I’m going to play my game.

“I’m not going to be afraid of any individual players. I respect everyone, but at the same time if we go and play our game and I play my game I believe that we will win.”

Zullo made his debut for Sydney against Wollongong in the Round of 32 but feels it was the subsequent win over Perth Glory that proved the turning point in the club's cup journey.

“Perth was a huge line in the sand for the team,” he said. “We managed to get through 120 minutes of really competitive football. It was both a mental and physical battle because conditions over there were really hard to play football in.

“It’s really galvanised us leading into this next round. The game against Blacktown City is full of importance for both of us. We want to make the semi-finals. For them it’s a massive day in their club’s history. To play against Sydney FC in Sydney and go to the FFA Cup semi-final as well as being a state league side.

“We know that they are a strong team, we are not underestimating them but at the same time we are very confident that if we go out there and play our game and do the things we can we should come away with the victory.”
