Ange Postecoglou took charge of his first Celtic training session on Thursday as he begins to assess his squad and where he feels improvements could be made.

With Scott Brown no longer at the club, central midfield could be somewhere he looks to strengthen with fellow Australian, Aaron Mooy, mounted as good option by former Newcastle United defender Steve Howey.

Mooy has spent the last 10 months out in the Chinese Super League with Shanghai Port who signed him for £4.05 million from Brighton, having made 22 appearances for the south coast club, and he has been linked with a move to Glasgow to play under fellow countryman Postecoglou.

The 30-year-old was a Manchester City player when he was starring at Huddersfield Town during their remarkable promotion season, which saw them finish the campaign with a negative goal difference and not winning a match in 90 minutes during the play-offs.

Brown leaving Celtic will have left a huge hole in the dressing room as well as on the pitch, so adding someone with Mooy's experience and technical ability could certainly help soften the blow and he could turn out to be a good signing, according to Howey who spoke exclusively to Transfer Tavern:

"I always thought he was good at Huddersfield and if his standard hasn't dropped from playing in China, then going to Celtic could be a good move for him."

Mooy, who has 43 caps for Australia, was hugely influential during his 120 appearances for the Terriers and when they were relegated into the Championship, the Australian international got a move to Brighton where he only ended up making 32 appearances before jetting off to China.

His time in China will have been disrupted because of the pandemic and he may want to leave and get back to playing regular football and try and help Celtic regain their crown at the top of the Scottish Premiership table.
