They might be faced with the Cup's most rampant attacking team, but Port Kembla's Franc Pierro says his side won't be on the defensive when they meet Wollongong United in the Bert Bampton Cup final on Sunday.

United have banged in a mammoth 14 goals in three games coming into the decider, including a remarkable seven-goal rout of Illawarra Premier League finals contenders South Coast United in a quarter final.

But Pierro insists they won't have it all their own way at John Crehan Park and warned his Zebras outfit would also be on the offensive on Sunday.

"We are not going to be one of those teams who scores one goal and parks the bus," Pierro said.

"We are going to go all out. It is a grand final so we will be giving it everything we have got."

Port have started to build closer to the form that saw them claim the League Championship, grand final double last season.

They are now seventh on the league ladder and poised to make a late season finals run.

Pierro is hopeful victory in Sunday's Cup decider can give those finals aspirations a boost.

"This is probably good for us. Getting a win will boost team morale ... from our kind of down start to the season," Pierro said.

"Hopefully we can get this under the belt and provide a more positive outlook."

Port last claimed the Bert Bampton Cup trophy in 2007, while United lifted the silverware just two seasons ago.

Reds' keeper Matt White said, although their last win was only recent, this title would still be hugely significant for his side.

"It would mean a lot to us. Especially for Ollie [coach Oliver Vrtkovski] in his first year coaching first grade," White said.

"We are going great in the league now with eight in-a-row, so a win would mean a lot.

"We have been working hard at training and the boys are really gelling.

"Ollie has really got the team sorted."

United's fantastic form has been heavily influenced by reigning George Naylor medallist Robbie Shields.

But White is adamant Sunday won't be all about the diminutive front man.

"I think we have quality all over the park. A lot of teams focus on Robbie but we still have quality up front," White said.

"Everyone can score great goals. We will just continue to attack Port and continue to pressure."

Sunday's final is at 1pm with the Youth Cup between Wests Illawarra and Bulli starting at 10.45pm.
