Plymouth Argyle boss Steven Schumacher has admitted he was inspired by Ange Postecoglou's style of play while at Celtic.
The Englishman took in the Hoops' 2-1 victory over Rangers in the League Cup final earlier this year and he was impressed with the Australian's tactics.
Schumacher detailed how a post-match conversation with Postecoglou convinced him to set up his newly promoted English Championship side in a similar fashion.
He told the EFL Podcast: "He [Postecoglou] was brilliant. I got the opportunity at the back-end of last season to go and watch Celtic against Rangers in the Scottish League Cup final and I was really impressed with how Celtic played.
"When I went and spoke to Ange and he explained it all, and explained the pluses and the negatives to the system, I just felt, ‘let’s have a go at it’.
"Eight games I think we’ve done really well in seven of them, and then in the ninth game obviously against Norwich we went back to a system we’re comfortable in.
"So I’m glad that the players have got a good understanding of it. I feel as though I’ve got a better grasp now to coach 4-3-3, but also, now we’ve got two systems that we can play and that keeps the opposition guessing.”
