Hiddink led the 'Golden Generation' at the 2006 World Cup in Germany, while his successor Verbeek was in charge of the Socceroos in South Africa in 2010.

Van Marwijk was appointed to coach Australia in April just before the 2018 World Cup in Russia.

Cahill is the only Socceroo left from the memorable Germany tournament, along with Mark Milligan, who has worked with all three Dutch coaches in the past 12 years.

Quizzed about the different approaches today, the 38-year-old said: "Guus Hiddink when we first got him, his training camp was the hardest, physically and mentallly. He got us prepared so well but he was very, very direct.

"He had his ways and there was no other way. Pim Verbeek was very lax, very laid back, and (Verbeek's assistant) Henk Duut, they were amazing guys, they were pretty much the opposite of the style that Guus was.

"And then you've got the guys now who are sort of in the middle - Bert, when he walks into the room, he has a presence, but he also has a softness about him that the players can relate to. He likes to have the odd joke with him and Mark van Bommel in front of the players.

"But his coaching style is relatable to football today, and also in simplifying, understanding the group. I've enjoyed the training because you'd think at 38 years old you can't learn. Well, the staff that he puts around him, I'm thankful that at 38 I'm learning something and I'm becoming a better player.

"I feel that we've been lucky to have the standard of coaches from Holland to come in and help, but I feel also van Bommel has been the one under the radar that has also made an impact with players."
