The Mariners will host Adelaide in the semi-final next week.

De Silva is confident Alec Stajcic's new-look Mariners, with a burgeoning strike force, can cause the Reds some problems.

"We’re not too concerned about how they’re playing, we’re just concerned about ourselves," he said.

"They’ve made some good signings this season, but they’ve lost the keeper and Goodwin. We have a style of play and we’re adaptable. We have a good squad this year, a lot of depth. We have a lot of fresh faces, a lot of good attacking power.

"We can very dangerous rotating players, players that can play different positions. The more we play together, the more we gel, the bigger threat we’ll be."

De Silva said Stajcic wants the Mariners to produce a fast-paced, attacking-focused philosophy this season.

"We want to play a really attacking style," the midfielder said.

"He loves to play combinations, one-twos and fast play. Hopefully an entertaining style of football and one that will help us win games. It's been great so far [under Stajcic], I’ve really enjoyed it. The results are telling that as well."

The former Perth Glory number 10 believes having the semi-final at Central Coast Stadium will be an advantage.

"That’s a good thing." De Silva said.

"We’re all very excited to be playing at home and in front of our fans. Hopefully we’ll get a big turnout."
