Since then, Wolff has been on the lookout for a replacement for his star man, making no secret of who his top target is by pursuing three-time world champion Max Verstappen.
While Verstappen leaving Red Bull looks unlikely, Wolff also has other options in the shape of Carlos Sainz and 17-year-old Andrea Kimi Antonelli.
F2 star Antonelli has emerged as the favourite in recent weeks to partner George Russell, but questions have been raised over his lack of experience and young age.
It has been suggested Mercedes may be better off hiring a short-term option to allow Antonelli's skills to grow over the coming years.
Now, Valtteri Bottas has revealed he is out of the picture to return to his old Mercedes team, despite being in regular contact with Wolff.
In an interview with Mirror Sport's Daniel Moxon, 10-time race winner Bottas said: "Filling a place for one year, I don't think that is what I want or need at the moment.
"For next year, I want something multi-year with a clear plan for the years ahead and work together for that time. I think that's what I need, a good challenge and a clear plan.
"If I just do one year, then you're back to square one again and looking at what's next. I'm good friends with Toto so, of course, we've talked about everything. It would be nice to have security.
"But I always knew when I signed everything that, in three years, it will be the same thing again. It's kind of exciting as well, in the end, if there is a change. I'm fine with the situation - it's been interesting - but I want to get it sorted soon. Then I'll be even happier again."
