With a potential $500,000 payday on the line against Amicale of Vanuatu, McFarland hammered home that Sunday's second leg could be the last time they play for the amateur club from New Zealand's largest city.
Auckland are in the driving seat after winning the first leg 2-1 in Port Vila on April 2 and Sunday's season-ending game will determine the Oceania champions and guarantee an invitation to FIFA's lucrative Club World Cup in Japan in December.
As is the nature of New Zealand's national league that runs during the southern hemisphere's summer, the team will disband immediately after the final whistle at Kiwitea Street.
"It's the last game of the season and who knows, in theory you could have a completely different staff or group of players representing Auckland City at the Club World Cup," McFarland told Reuters via telephone.
"It's (an) amateur (club) but every player needs to hold a contract that expires at the end of this game. So it's all about this weekend... and getting Auckland City into the Club World Cup."
"In reality, a lot of players will be motivated to go back to the Club World Cup and regardless of who the coach is they will want to retain the core of this team," he added.
"But (the message), is it's all about this weekend."
"I reckon the players are the most committed in the country," he said. "We train four times a week and play one match so that's five times a week they're all together.
"I don't see any other sides outside of the national team doing that on a regular basis. That's a huge commitment to ask of people who have normal jobs.
"So the players and staff have a very professional outlook but the board and all backroom staff are very organised as well.
"It's run on the dedication of volunteers... they just love the game so much."
"It was an incredible atmosphere," Mc
