The 24-year-old wanted to emulate one of the Chelsea star's former teammates.
Former Midtjylland manager Glen Riddersholm has explained to the Daily Record how he convinced Celtic's latest signing to model his game around Chelsea great, John Terry, rather than the Blues skipper's former teammate, if he wished to succeed in the British game.
Erik Sviatchenko has signed a four-and-a-half year deal after completing a £1.5m move to Parkhead (via BBC Sport), and Riddersholm - who is now the head coach at AGF Aarhus - has explained how a trip to England when the defender was a youngster convinced him to look to emulate the game of Terry, rather than the player that Sviatchenko initially wanted to be like.
"But I had a lot of talks with him and I said: 'Forget all about that. Become a defender like John Terry instead.'
"His former colleague at Midtjylland was Winston Reid and I sent him on a trip to England with him to see how the big defenders played.
"I said: 'Go and see Terry and forget about Luiz.'
"If you want to fit into British football, you need to able to defend your goal and be strong with leadership."
While David Luiz is arguably one of the most exciting defenders to watch in the current game - and appears to have inspired the likes of former Hoops man Virgil van Dijk with his marauding runs forward and his amazing free-kick taking ability - Terry has been one of the strongest and most reliable centre-backs that the Premier League has ever seen.
And Ronny Deila will be hoping that the 24-year-old's former mentor's words will continue to influence the Denmark international during his career with the Scottish Premiership champions, as the addition of a player with similar attributes to the Blues legend will surely prove a great signing for the Bhoys.
