Wolves coach Nahuel Arrarte is acutely aware of the opportunity on offer to the South Coast squad when they meet Manly United in the Waratah Cup on Wednesday night.

In a knockout semi-final, the Wolves have the chance to march into an unlikely Cup final at Lambert Park on Sunday, July 6.

"This is an opportunity that most players won't get or some players go through their whole careers without playing in a grand final or winning anything," Arrarte said.

"From a coaching perspective it is a similar thing but obviously nothing changes from my end.

"It will be a process like any other game ... it is making sure that the boys are up to it and keep doing what they are doing."

Arrarte was adamant his squad would bring in the same attitude that saw them progress to the final-four of the tournament into Wednesday's stoush with Manly.

"Every game is a grand final and the boys have shown that in every game we have played," Arrarte said.

"Even with the Cup, both teams are playing for the opportunity to win some silverware. It is massive for the club and the region."

The last time the pair clashed was at WIN Stadium a little over a month ago in a match the Wolves reignited their season with an emphatic 6-1 victory.

But Arrarte believes the Wolves can't afford to buy into United's performance on that day.

"It is not about what Manly were doing five or six weeks ago," Arrarte said. "It is about what Manly were doing in the past few weeks.

"It is the same as us. If you look at the Wolves five or six weeks ago we are not the same team that are we now."

During the Wolves recent impressive run, Arrarte and assistant coach Michael Santalab have made no secret they are willing to modify the Wolves starting side.

It is set to be the case again on Wednesday.

"We have got 20 players plus the guys in the 20s who have played so it is not so much about rotating, it is about whoever is out there is what we think is best for a particular week," Arrarte said.

"Michael Santalab and I don't think we have just a first eleven, we have a squad. Anyone is as good as anyone so we will choose what is best for each game."

In the other semi, Sydney Olympic take on Blacktown City FC at the Belmore Sports Ground.
