During a 19-year playing career that yielded 123 bookings and 12 red cards, Muscat was once branded the “most hated man in football”.
Post-retirement, he revealed, external former Rangers manager Alex McLeish did not trust him to play in an Old Firm derby during his brief spell at Ibrox.
It is to the Australian’s credit that he has since gone on to somewhat shake off his hot-head image in an impressive 13 years in management.
His glowing CV attracted Rangers two years ago, but he reportedly missed out on the job when the club opted for Philippe Clement instead.
At that time, former Rangers team-mate Neil McCann told BBC Scotland that the Ibrox side would be getting someone with “presence” who “understands the league, the intensity, the rivalry and how to get the job done”.
Muscat was then first-team boss at Yokohama F Marinos, where he won 2022 J-League after taking over from Ange Postecoglou following his exit for Celtic.
He also succeeded Postecoglou at Melbourne Victory after a period working under the current Nottingham Forest head coach.
It was in Melbourne where Muscat’s managerial career began, winning the A-League Championship twice in five-and-a-half years before his move to Japan.
Runners-up spots in the J-League in 2021 and 2023 bookended his 2022 triumph in Yokohama.
Muscat became a title winner in a third different country last year in China, and he is on the verge of another with just four games remaining as his side sit top with a two-point lead.
Across his managerial tenures in Australia, Japan and China, his win rate stands at 54%, with his teams scoring an average of 1.9 goals per game while conceding 1.2.
His Shanghai Port side scored 96 times in a 30-game league-winning campaign last year.
Those numbers suggest this is a coach who can win while implementing a front-foot approach. How that translates to Scottish football is unclear, though.
