Former world champion Jenson Button may reportedly be in the run to replace Valtteri Bottas if the latter decides to leave Williams in the next Formula One season.
According to the BBC, Bottas is the primary target for Ferrari if the Italian motor racing giants decides not to retain Kimi Raikkonen alongside Sebastian Vettel.
Although Ferrari and Williams are said to have had a discussion on Bottas' transfer, no official agreement has been reached.
Button, the 2009 world champion, would see his career completing a full circle if he rejoins Williams in 2016.
The 35-year-old driver made his F1 debut for Williams in 2000 before moving on to Benetton/Renault, BAR - which became Honda and then Brawn - and finally McLaren.
