Hamilton is to move for pastures new at the end of this season, ditching his Mercedes team for Ferrari, where he will look to claim an unprecedented eighth world title.
Vettel, meanwhile, has been out of the sport since 2022, when he retired following two rather underwhelming seasons with the Aston Martin team.
Despite this, the German has consistently failed to rule out a return, with the four-time champion still only 36 years old, six years younger than Fernando Alonso and three years younger than Hamilton.
"A German driver, a multi-world championship-winning driver and someone who has got amazing values and continues to take this team forward.
"There are so many great people in this team and as drivers there are some that are more selfish than others, there are some that are good drivers but perhaps not the best within team environments. I don't know because I've not been in with all of them, but I hope they find someone great.
"They've already got George [Russell] and he's perfect for the team so finding a good match alongside him. They've got so many options."
