"I always want us to be on the front foot and taking the game to teams."
No one was getting ahead of themselves this week, Calvert said.
"That's the thing we have spoken about the most. We haven't achieved anything yet.
"If we do get the win then the season carries on, you certainly can't get into holiday mode."
The regular season will be followed by a three-week Central League knockout tournament.
It doesn't change the end-of-year standings.
If Athletic emerges victorious this weekend, a playoff against the Capital Premier League winners will determine who is promoted to the New Zealand Football Central League next season.
The team last lifted the Federation Cup in 2014.
Last weekend's win featured 60 minutes of the best football Athletic had played all season, Calvert said.
"We scored our goals from different scenarios and it was a shame we didn't get a couple more.
"We made it very hard for them to have any clear-cut chances in the game as well.
"That was pleasing for me, especially in my position (goalkeeper). Keeping clean sheets is massively important and it's important to keep those habits."
Athletic's last fixture of the season is at home to Massey University.
The game kicks off at Wembley Park at 2.45pm on Saturday, August 6.
