While world champions Red Bull are likely to want to replace Sergio Perez at the end of the season, Mercedes will have to replace their seven-time world champion, who's going off to chase his 'childhood dream'.
Now, the Mercedes team principal has revealed quite how drivers are putting their pitch across to him about why they should replace Hamilton.
“Yeah, I think it's the full spectrum,” Wolff told CNBC.
“We have, as you can imagine, the first day yesterday had quite a lot of phone calls and WhatsApps, and we're going to take our time.
“I think the spectrum is from the very young talent which could be the future for a long, long time to all the way to the other spectrum, lots of still performance and knowledge.
“So I'm not sure where this is going to end. But the next few months are going to be interesting in evaluating all those options.”
