Celtic defender's insight into “brave” Ange Postecoglou approach: 'Every player knows exactly what to do in their roles'

Celtic’s open, attacking approach under Ange Postecoglou, and certain unusual facets of that, were once the subject of feverish debate. No longer.

Results have determined that. But Anthony Ralston would contend that it is what has underpinned those results that has closed off any questioning. The Scotland international slotted in seamlessly to the Celtic side that dismantled Motherwell 4-0 on Sunday, having had to settle for a role on the bench as his rival for the right-back berth Josip Juranovic made a huge impact in the 3-0 slaying of Rangers in midweek.

Right across his team - with the exception of central defence - in the past week Postecoglou dropped players in and out as Celtic extended their recent rich streaks to 23 domestic games unbeaten, and five straight league successes – a quintet that has eased them to the top of the cinch Premiership. The quality of Celtic’s personnel has allowed for this fluidity, but so too has Postecoglou’s drilling of his men on the training pitch, Ralston maintains. “We’ve got a great squad and the good thing about it is that everybody’s ready to play when they’re called upon,” he said. “They know exactly what to do in their roles. We’re in it together and it’s important we carry on that way through rest of season.”

It’s not a way I’ve played before but it’s effective and I’m enjoying doing it,” the
