Williams deputy team principal Claire Williams has reiterated her stance on Robert Kubica's short term future, insisting there are no plans to replace the Pole before the end of the 2019 season.
Kubica's miraculous return to F1 has been anything but an easy ride, the 34-year-old having been consistently outpaced by rookie teammate George Russell.
However, the pair's performance has also been capped by the limited potential of Williams' FW42, a car whose speed has fallen well short of expectations.
Still, in light of Kubica's results, speculation has emerged that the Pole's season could come to a premature end.
"I find speculation quite frustrating because unless you actually know on the inside, you don’t know what’s going on," Williams said.
"Our relationship with Robert is as strong as it was. He’s getting his head down and he's doing what he needs to do, and we’re trying to do everything that we can to give him a better car so that he can perform at the level he wants to.
"As far as I’m concerned, there are no frustrations from our side. I’m sure he has a level of frustration because he doesn’t have the equipment that he would like at the moment."
Speaking of equipment, Williams also denied that Kubica was being supplied with an inferior car compared to Russell, as pundits have suggested.
"There is absolutely no difference between George and Robert’s car," she said.
"If anything else, we don’t have the budget to create two different types of race cars. So this speculation is just crazy.
"We do everything to make sure that both George and Robert have the same equipment, the same test items at every race weekend that we can to give them the best opportunity going into Saturday and Sunday."
