The Brisbane Roar captain and record holder for the most games played has announced his retirement from professional football at the end of this season.

McKay, 36, is set to play his 271st A-League appearance for Brisbane Roar this Saturday night, the only A-League club he's ever played for during a long career which also saw him in action overseas in Europe and Asia.

“I’m grateful for everything football has given me," he said today. "I’ve had an enjoyable career with plenty of highs and lows but I’ve always had a smile on my face and that’s what’s made it for me.

“Thank you to all the people who have supported me, my parents, my friends and of course my wife Amanda and our two boys. I’m very grateful for the sacrifices that have been made to help my career.

“I’ve always tried my hardest and I think that’s what has made my career last as long as it it has - I’ve always given my all.

“The thing I cherish is being able to play and work alongside some incredible people. I was there from day one at the Roar and played with some immense players with a great work ethic, which has been really special."

A two-time Gary Wilkins Medal Winner, proud Queenslander McKay made his debut for Roar in its first A-League fixture on August 28, 2005.

The midfielder famously lifted the Roar’s first A-League Championship as Club Captain in 2011 before being an integral part of the Roar’s Championship & Premiership winning season in 2013/14.

He currently sits fourth on the club’s all-time goal scoring charts with 26 goals to his name.

Roar CEO David Pourre paid tribute to the club’s longest-serving player.

“On behalf of everyone involved in the Brisbane Roar, and the broader football family in Queensland who have been part of Matt’s journey, we would like to thank Matt for everything he has given to the Club,” Pourre said.

“Matt has been a terrific servant over his 12 seasons at Brisbane Roar & played a pivotal role in the many successes we have had over the years.”

“He’s an admired leader & a fierce competitor, he leaves behind a legacy unlike any other before him at Brisbane Roar.

“A champion club man and wonderful person, he will always be in the hearts and minds of the Brisbane Roar members and supporters.”
