Despite putting together a good display to see off Central Coast Mariners on Monday, Musialik believes Sydney have plenty of improvement left in them yet.

"I'd say it was up there. This weekend we played well and we came away with a win (but) we still missed plenty of chances and it probably could have been a lot more," said Musialik

The 24-year-old was at the heart of the action, delivering a pinpoint cross for Terry McFlynn's match-winning goal.

Despite his strong personal input, the holding midfielder preferred to focus on the team performance.

"I'm happy to get the assist but at the end of the day it doesn't come down to individual things," he said. "I think as a team we showed a lot of guts and determination."

Coach Vitezslav Lavicka echoed Musialik's sentiments, applauding his side for its commitment and style.

"We played well in shape, we tried to play quickly especially in attacking and scored an excellent goal," he said.

Sydney FC's fifth win of the season sets up a top-of-the-table clash with arch-rivals Melbourne Victory on Friday night.

Despite a very short turn-around the Sky Blues travel to Melbourne on a wave of confidence:.

"We'll definitely go down there very positive and chasing a win," said Musialik.

"It's always a big game against Melbourne Victory (and) we're expecting a big crowd down there," added his midfield partner, Terry McFlynn.

Sydney's squad will be boosted this week by the return of Kofi Danning, Rhyan Grant and Matthew Jurman from the U20 World Cup in Egypt and John Aloisi is also on track to come into consideration for the clash with second-placed Victory.

The round-10 blockbuster will be played at Etihad Stadium on Friday night. Kick-off is at 8pm.
