Ange Postecoglou's former club South Melbourne have congratulated Celtic after the win over Rangers in the Viaplay Cup final - adding a 'we told you' message.

The Australian side shared a social media message with Celtic after the victory at Hampden as they hailed Postecoglou for his latest trophy triumph in Scotland.

A Kyogo Furuhashi double saw Celtic lift the trophy after a showpiece final with Alfredo Morelos goal back for Rangers rendered merely a consolation.

As celebrations erupted among Celtic supporters, South Melbourne joined the party by heaping praise on Postecoglou.

A Twitter message read: "Hey @CelticFC, We told you our boy was good.

"Congratulations Ange on winning yet another trophy after his 2-1 cup triumph over Rangers this morning."

After the match, Postecoglou said: “The overwhelming feeling is relief. People think you are jumping for joy, but it’s relief as you know how much it means to people: the players, everyone at the club and the supporters.

“You carry that burden for 95 minutes and when the final whistle goes it’s just relief. You watch the players, the fans, and what it means to them. I take great pride in it.

"It’s a day I’ll remember forever. We’ve been consistent for a very long time. We don’t let our standards slip in terms of our football.

“We had to earn it, we played some fantastic football and just couldn’t put them away. You know Rangers are going to come at you, but we defended well. We got through a sticky patch and then Rangers had to open up, and we had chances to get a third.

“We haven't had many off days because we never look too far ahead and never look too far back. That’s why we have been so relentless in our approach. The reason I push them is for days like this. Come Tuesday we focus on a tough game at a tough venue.”
