Robert Kubica has denied reports that he could be set to drive for Haas in 2019.
Currently the Williams reserve, former BMW and Renault driver Kubica has also been linked with Force India for next year.
"I do not read gossip," the Pole told Eleven Sports at Hockenheim.
"I have always preferred to do things quietly. I am having some conversations, but not with Haas. At the moment I am not talking to them."
Another rumour is that Force India will be Kubica's racing destination for 2019, possibly to be Lance Stroll's teammate.
"I do not know if Lance is going there, so at the moment it's pointless to look ahead and create stories," he said.
"I'm not saying yes and I'm not saying no about who I'm talking to.
"It won't be easy, because many young drivers with big budgets and opportunities want to get into F1, and there are teams that require money.
"So there are some limits and some that end there."
The 2018 F1 calendar continues this weekend with the Hungarian Grand Prix.
