The former Australia boss told Celtic TV: “It is important not just for him (Furuhashi), I said it to the players, that is the expectation of our fans.

“Of course they love the goals, they love the exciting things but they want to know you are putting in a shift because they do on a daily basis.

“They spend their hard-earned on getting a season ticket to see them play, they want to see the people representing them put in a shift as well.

“I knew Kyogo has that anyway, he works hard but for me that was the most pleasing thing, that all the players bought into that.

“They are willing to do the hard work and show the supporters that they are going to give everything until the final minute.

“We could have maybe relaxed in the last 10-15 minutes but even after we scored the sixth we had the chance to score another one and I think that is important that the players understand that that is what the fans want to see.”

Postecoglou is pleased with the form of right-back Anthony Ralston, who scored his second goal of the season against Dundee, who has been proving doubters wrong with recent performances.

He said: “He has bought into how we want to play. Anyone who knows how I want my teams to play, I am fairly demanding of players, particularly in certain positions where they are used to doing things a different way.

“It takes a lot to buy into that but to be fair to Anthony from the first training session he has been really keen to understand the role and how I want him to play and I think he has done exceptionally well, not just from an individual perspective but how he helps the team.

“I think he is enjoying himself which also makes a massive difference and I have been really pleased with his progress.”
