Hamilton at the time still had one year left on his Mercedes deal, but speculation was growing over what his next move would be.
And Camilleri admitted that Ferrari chairman John Elkann had held “conversations” with Hamilton.
The 66-year-old also said Ferrari were “very flattered Lewis in particular, and other drivers, want to join us”.
Of course, Hamilton has since signed a one-year extension with Mercedes, but questions still remain on what he plans to do in the long term.
Mercedes remain the team to beat on the grid, but new regulation changes in 2022 are expected to shake up the sport and there is likely to be ongoing speculation over what Hamilton decides to do next year.
