Niki Lauda has suggested Mercedes will keep Lewis Hamilton beyond 2018.
In the past days, as Ferrari announced it is keeping Sebastian Vettel, there have been rumblings Hamilton now wants a new three-year deal at Mercedes.
"Ferrari is a dream for every driver," the triple world champion said, "but I guess I will not drive there at least in the next three years."
But Mercedes chief Toto Wolff says any talks about a new contract for Hamilton will be delayed until the end of the year.
Lauda, the Mercedes team chairman, told Osterreich newspaper: "Lewis is our best driver and we all love him.
"We will therefore find a solution for the future with which everyone can be happy."
