Hamilton has been integral to Mercedes powering ahead of Ferrari and Red Bull since joining them from McLaren in 2013.
It’s only fair for him to point out to Wolff how his World Drivers’ Championship glory has helped Mercedes financially.
Wolff has confirmed talks are ongoing over a new deal which will see Hamilton’s efforts and quality rewarded.
“Don’t worry, he sent me a number a few weeks ago,” Wolff said, when it was pointed out Hamilton has contributed to making Mercedes stronger financially. “I sent him another one last night. We are starting to approach each other.”
