Bottas move to Mercedes to replace retired world champion Nico Rosberg is signed and sealed if the comments of Williams' deputy team principal are anything to go by.
"It has been dragging on and I think everyone wants to know, probably more who is going to be Lewis’ team-mate next year, and of course whenever Nico made his announcement we knew the call was probably going to come from Toto,” Williams told Sky Sports News HQ.
"It is a great opportunity for Valtteri and he has given a lot to Williams. We’ve always said if we can make this happen on terms that are positive for Williams then it is probably the right thing to do.
"No-one needs or wants a driver in your team that really wants to be somewhere else. It is not nice either to stop a driver who has such a great opportunity, particularly at this point of Valtteri’s career, but it has to work for Williams and that is what we’ve been working hard on over the past six weeks."
Williams added that an epilogue to the ongoing sage was around the corner, while she also had no doubt that Felipe Massa, rumored to delay his retirement by a year, still has what it takes to perform at the highest level.
"We are nearly there, we are at the tail end of it and hopefully we’ll be able to make an announcement this coming week."
“If Felipe was to come back I don’t believe there would be any lack of competitive spirit within him. We also wouldn’t bring a driver who we had any concerns over his ability to do the job for us."
