This would leave a vacant seat at Williams, which Bottas could potentially fill if his former team are interested in a reunion.
However, Mercedes team principal Toto Wolff recently said that Mercedes reserve drivers De Vries and Stoffel Vandoorne deserve to be in Formula 1.
The pair compete for the Mercedes EQ Formula E team alongside their F1 reserve driver duties, and following Wolff’s comments, it was speculated that De Vries could join Williams next year.
This would potentially leave Bottas without a seat on the grid, but the Finnish driver has said he is not concerned by Wolff’s praise for De Vries and Vandoorne.
“I’m not aware of those sayings,” Bottas replied when asked about Wolff’s praise for Mercedes’ two reserve drivers.
“I don’t really read F1-related media reports, so it’s the first time I hear anything like that.
“Of course, you will always try to praise your drivers, whether it’s in different categories, and they are very good drivers.
“There aren’t many seats in F1 but it’s not really my concern at the moment and is nothing that’s on my mind,” he concluded.
De Vries today won the Formula E title, boosting his chances of landing an F1 drive in 2021.
