Williams deputy principal Claire Williams has claimed that Jenson Button back at the Grove-based outfit would be a 'great headline'.
With current drivers Valtteri Bottas and Felipe Massa both out of contracts at the end of the season, Williams has admitted that they have been chatting to other drivers around the F1 paddock.
However, she also added that it is just to keep their bases covered in case of any unforeseen circumstances that may arise, saying that the team are extremely happy with what Bottas and Massa are doing.
"Button back at Williams' is a great headline," Williams told Sky Sports of their interest with the 2009 World Champion.
"He started his career here, he's a world champion and extremely intelligent when it comes to building a team around him and helping the engineering side develop the car.
"Of course he is going to be an attractive proposition if he is available. But we are talking to a lot of drivers in the paddock at the moment – and he may or may not be on the list."
"We are talking to [Bottas and Massa] and we are having other conversations with other drivers in the paddock to see what other opportunities there are.
"But that's not to say we aren't happy with the job Valtteri and Felipe are doing. We have a great line-up, but no decision has been made. We just have to work through the conversations."
The speculation stems from a rumour that was reported earlier in the season that reserve driver Stoffel Vandoorne is being looked at as a possible replacement for Button at McLaren.
