Aaron Mooy netted his fourth goal in four games as Celtic swept past St Johnstone 4-1 at McDiarmid Park on Sunday.

Ange Postecoglou's side restored their nine-point lead at the SPFL Premiership summit with the victory, which was secured thanks to an Andy Considine own goal and strikes from Kyogo Furuhashi, Mooy and David Turnbull.

Mooy, who earned man-of-the-match honours for his display, celebrated his goal by looking toward the camera and making his hands into the letter S.

The 32-year-old Australia international's wife, Nicola, confirmed on social media that the celebration was a nod to the couple's daughter, Skylar.

Sharing a photograph of her husband, Nicola's caption alongside it read "S for our daughter x".

When asked by the BBC after the St Johnstone victory what it is boss Ange Postecoglou asks of him, Mooy replied: "There's lots of details that go into that. Just positionally, in movements, defensively, when have the ball and when we don't. 

"There are lots of things but I'm just trying to improve and get better at it. Yeah, that's it... it's simple.

"It's a good team to play in, it's enjoyable. We play good football, there's lots of movement. When I have the ball there are lots of people making runs - that's what I like. I like to play the ball in behind sometimes and yeah it's an enjoyable place to play."

On his superbly-taken goal, Mooy added: "I sorta knew what I was going to do in my head before the ball came," Mooy said of his goal. "My first touch was good so once I took that first touch I knew I could lift it over him [Saints goalkeeper Remi Matthews]."
