De Visser has long been a talent adviser to Blues owner Roman Abramovich.
And he recalled to VBTL: "I scouted him, but nobody wanted him.
Abramovich would regularly call De Visser for help and at one point the Dutchman raised the name of David Luiz again.
“Then Abramovich called: 'Piet, we need a centre-back. I said: 'Roman, I told you before, for nothing you could have David Luiz!'
"He took him for a lot of money."
