Graham Arnold's definition of becoming the greatest team in A-League history is whether Sydney FC can eclipse the points' record for a single season.
Defender Alex Wilkinson's is somewhat more specific.
Because, of all the statistical barometers of being the best -- and the Sky Blues are on their way to claiming several more -- Wilkinson is in the business of stopping goals.
It's no surprise, then, that he's targeting the record for least conceded goals in a season.
The league leaders are set to complete the campaign comfortably below the current mark of 19, testament to the efficiency of the 32-year-old Socceroo and his teammates.
The sides who set that record, Sydney (2006-07) and Adelaide (2008-09), did so in eight-team competitions, while Arnold's men must play six additional games as part of a 10-team league.
With exactly that many matches remaining, only 11 goals have slipped through the cracks.
"That's personally a record I would love to get, being a defender," Wilkinson told AAP.
"I'd love Sydney FC to be in the record books for that."
While Arnold's defend-from-the-front success is the envy of chasing rivals, so are calm heads at the back like Wilkinson.
Having played 90 minutes in all but one game, the former Central Coast Mariners captain is the stable constant, amid central defensive reshuffling that's partnered him with five different players including new Dutch mainstay Jordy Buijs.
He's been integral to Sydney's 11 clean sheets, and that record of 14 in also in sight should goalkeeper Danny Vukovic, the overall record-holder for clean sheets and A-League appearances, manages another four.
"Clean sheets is something that myself and the back four, and obviously Vuka, pride ourselves on," Wilkinson said.
"We were just saying the other day after the City game that we haven't had a clean sheet in three or four games and we're a bit disappointed with that.
"We've got to tighten up a bit -- we've conceded a few sloppy goals.
"Squad-wise though, the goal is 58 points. That's our opportunity to get into the history books and be the best team that's competed in the A-League so far."
Last weekend's 3-1 win over Melbourne City made the Sky Blues the fastest team to reach the 50-point mark and guaranteed them a top-two finish and Asian Champions League qualification.
It also brought Arnold's bid to surpass Western Sydney's (2012-13) 57-point season even closer to reality, with Friday's top-of-the-table blockbuster against Melbourne Victory effectively set to hand them the Premiers' Plate.
Wilkinson stressed nothing would be decided until mathematics determinesd it.
"But I guess for them [Victory], they feel that they have to come here and win to have a chance to bridge the gap," he said.
"That's going to make for an exciting contest."
