Mercedes boss Toto Wolff says contract talks with Lewis Hamilton are going well and is confident his star driver won't walk out of the team without giving notice.
This time last year Mercedes was on the hunt for a replacement for Nico Rosberg after the 2016 world champion unexpectedly retired with two years left on his contract. Wolff drafted Valtteri Bottas into the team as his replacement, but had to negotiate with Williams to get the Finn out of his 2017 contract.
Hamilton's current Mercedes deal expires at the end of 2018, and while Wolff is willing to allow Hamilton a degree of flexibility, he is confident his star driver won't leave the team in the same way Rosberg did.
