Melbourne City insist their A-League Men title defence remains firmly on track despite a bruising week that delivered both a humiliating heavy defeat and the loss of one of their most important players. The reigning champions are determined to respond strongly after being thrashed 6-2 by Macarthur, even as Socceroos defender Kai Trewin finalised his move overseas to Major League Soccer outfit New York City FC.
The circumstances have tested City’s resilience. The defeat to Macarthur marked their heaviest loss under championship-winning coach Aurelio Vidmar and came at a time when the club is also dealing with squad disruption, injury uncertainty and the emotional impact of tragedy off the pitch. Yet internally, the mood is one of resolve rather than panic.
Trewin’s departure was confirmed on Wednesday, with the 24-year-old centre-back sealing a transfer to City Football Group sister club New York City FC. The move brings an end to a rapid rise for the defender, who has become a regular for Melbourne City and pushed himself firmly into World Cup contention with the Socceroos.
Notably, Trewin did not feature in last week’s loss to Macarthur, a result that stunned supporters and exposed uncharacteristic defensive frailties. For Vidmar, however, the scoreline did not tell the full story, and his message to the playing group was one of accountability rather than despair.
“We had a really robust discussion yesterday,” Vidmar said.
“To be honest, the effort and everything was there, but we really got punished with our simple mistakes, our basic mistakes, and if you have a look at all the goals, they were just very simple mistakes, which is very uncharacteristic for us.
“So yep, absolutely got to be better, but we're resolute as ever. It was a really disappointing result.
“But we can't sit there and cry about it. We've got just a couple of things, got to make ourselves better, always looking and wanting to improve.
“We are in a really good headspace, and sometimes you get a bit of a jolt when it's a heavy defeat like that, but we've got to just keep coming back and keep showing ourselves.”
The emphasis on response has been a defining feature of Vidmar’s tenure, and City’s recent history gives weight to that confidence. Over the past few seasons, they have repeatedly shown an ability to absorb setbacks, reset quickly and reassert themselves as one of the competition’s benchmark sides. While the Macarthur loss was painful, it is viewed internally as an aberration rather than a sign of systemic decline.
The loss of Trewin, however, presents a more lasting challenge. The defender has been central to City’s structure, offering composure in possession, strong aerial ability and a growing leadership presence. His departure mid-season is not ideal, but Vidmar was quick to balance the disappointment with pride in the player’s progression.
“As disappointed as I am that we're losing him - because I would have preferred to lose him at the end of the season - I'm pleased for him,” Vidmar said.
“If he continues his form, he's able to play on a weekly basis, I think he's a shoo-in (for the World Cup).”
That assessment underlines how highly Trewin is rated within the club. A regular starting role in MLS with New York City FC could significantly boost his chances of cementing a place in Australia’s World Cup squad, particularly if he adapts quickly to the pace and physicality of the league.
From City’s perspective, the challenge now is reshaping their defensive unit. New signing Harrison Delbridge, brought in to bolster the backline, will not be available for Friday’s away clash against Wellington Phoenix, limiting Vidmar’s immediate options. There is also uncertainty around the availability of Daniel Arzani, with the club yet to confirm whether the attacking recruit will feature.
Sitting eighth on the ladder, Melbourne City are conscious that the margins in the A-League Men remain tight. A strong run of results can quickly propel a team back into contention, while inconsistency can just as easily see them drift. The coaching staff believe their underlying performances still provide a strong foundation, despite the blowout loss to Macarthur.
Beyond the tactical and personnel issues, the club has also been rocked by the death of respected former A-League Men and A-League Women coach Rado Vidosic, who passed away after a short battle with cancer. The news has had a profound impact on players and staff across the City Football Group.
Vidmar shared a close professional connection with Vidosic, having completed his professional licence alongside him before eventually replacing him as Melbourne City coach. His tribute reflected both personal loss and the wider influence Vidosic had on Australian football.
“Devastating news. A guy that's done an enormous amount of great work in football in this country for many, many years and also served this club with high distinction in the women's game, the academy space, and also the first team here at City,” Vidmar said.
“It can be a harsh environment in football sometimes, but he always was the same person, a true gentleman right through his time as a football coach.
“So it was really devastating news for everyone, and he's going to be missed for sure.”
The emotional toll of that loss adds another layer to an already challenging week, but within the club there is a sense that such moments can also strengthen unity. Senior players are expected to shoulder greater responsibility, both on and off the pitch, as City attempt to honour the standards that have defined their recent success.
Friday’s trip to Wellington looms as an important test of character. The Phoenix are traditionally difficult to beat at home, and City will need to show defensive discipline and sharper execution to avoid a repeat of last week’s errors. For Vidmar, the focus remains on improvement rather than overreaction.
The departure of Kai Trewin may mark the end of one chapter, but Melbourne City are determined it will not derail their season. With belief in their systems, confidence in their squad depth and a clear-eyed assessment of what went wrong against Macarthur, the champions are intent on proving that a heavy defeat and a high-profile transfer will not define their campaign.
