The former Australian national team coach, Ange Postecoglou, is said to be the front-runner for the Celtic managerial post.

Despite only being a member of the Rangers squad for three games in the 2011/12 season, McKay claims that he gained a better understanding of Scottish football and thinks his former manager, Ange could develop the national game.

Sky Sports asked McKay about Postecoglou’s use of an offensive playing style with both Brisbane Roar and Australian national sides, which has sceptics.

“Maybe people don’t rate Australian coaches or football but he likes a challenge and he’ll love the fact people are doubting him already.

“The club (Celtic) need a massive rebuild after what happened last season so he’ll get in there and given time he will play an attacking style of football, possession-based but fairly direct as well.

“It’s a case of if the opposition score six, he’s happy with his team scoring seven – he’s done that throughout his career. He’s not scared to get out there and take it to teams.

“From my knowledge of Scottish football that is something I think the fans will enjoy.”

In the two years before assuming control of the Australian national team, Postecoglou won two A-League titles with Brisbane Roar and steered the national team to qualification for the 2014 World Cup, where they subsequently won the Asian Cup in 2015. Having guided the Japanese side to their maiden J League championship, Greek-Australian coach Ange became the first foreign manager of Yokohoma Marinos.

Many people have found it difficult to accurately judge the magnitude of that success, but McKay praised Postecoglou’s managerial acumen. He commented, “He’s a great man-manager first and foremost, and his success with Brisbane Roar and the national team is proof of that. He has also shown that with the current club he manages, the Marinos.

“Tactically, he’s very good, he sets his team up well and brings in players who will do a job for him and will challenge everyone to be better.”
