Ange Postecoglou joined touching Celtic Park tributes to Lisbon Lion Bertie Auld on Tuesday.
Postecoglou, Celtic captain Callum McGregor and chief executive Michael Nicholson laid a wreath in memory of the legendary figure.
Auld's sad passing aged 83 was announced on Sunday with tributes flooding in for the beloved Celtic figure.
In a moving scene at the feet of the Billy McNeill statue outside the ground, celebrating the iconic European Cup win, the club representatives took a moment of silence to remember Auld.
The wreath was placed alongside mountains of flowers and messages of condolence outside the stadium.
Team replica shirts were also left in his memory with tributes along the bars of the stadium.
Candles and flowers were also left along the Celtic Way approaching the ground.
Postecoglou has been among countless figures to honour a giant of the Scottish game.
He said earlier this week: “With Bertie's passing a family and a club has lost a true legend and a great man.
“All our heartfelt thoughts and prayers go sincerely to Bertie's family for their tremendous loss of someone so dear to them.
“I know Bertie was one of the true Celtic greats, leaving his mark indelibly on the club and our supporters by reaching the very summit of footballing achievement, but also through his unique personality.
“Big, special football clubs are built on major figures like Bertie and we should all forever be grateful to him for all he achieved and all he was. I know his spirit will flow through Celtic for ever.”
