A hamstring injury to Tom Rogic was the only sour point for manager Ange Postecolgou as Celtic celebrated a 3-1 Scottish Premiership victory at Hibernian to close in on top spot.
While Socceroos teammate Martin Boyle scored for the hosts to remain equal top scorer in the top flight, it was the performance of Rogic in the first half at Easter Road that garnered most attention.
In a rampant opening period for Celtic, in which they led by three before Boyle netted for the seventh time in the league this season, Rogic provided a brilliant assist and ran the show in what Postecoglou described as their best performance of the year.
"I thought our first half was as good as we've played this year, especially away from home against a good team," Postecoglou told Celtic TV.
"We were really fluent and dynamic and scored some good goals and it was pleasing to see as that's the kind of team we want to be."
Tony Ralston and Cameron Carter-Vickers both struck early before Rogic left a trail of defenders in his wake before Jota rolled the ball across goal for Kyogo Furuhashi to tap in on the hour mark.
Boyle responded for fifth-placed Hibs on 37 minutes when he nodded home from a corner.
It proved nothing more than a consolation goal while Celtic were not as dominant in the second half after Rogic was replaced in the 44th minute.
Postecoglou said Rogic "felt something" in his hamstring.
"It's one we will have to assess - he's played a lot of football but I'm hoping it's not too bad because in the early bits I thought he was outstanding," the manager said.
Celtic have won four league games in a row as former Socceroos coach Postecoglou is rewarded for sticking to his philosophy and style of play - despite earlier criticism when results weren't going his side's way.
The second-placed Hoops sit just two points behind leaders Rangers, who fought back from two goals down to draw 2-2 with Aberdeen at Ibrox.
Tokyo Olympian Cameron Devlin continues his impressive form for third-placed Hearts, with another 90 minutes in their 1-1 draw at St Johnstone.
The 23-year-old is enjoying a fruitful start to his career in the UK - playing every minute of Hearts' past five league games since his debut off the bench last month.
