Robert Kubica has said fans and the media should not compare his times in testing to fellow Williams driver Sergey Sirotkin.

Kubica lost out to Sirotkin for the final seat on the 2018 grid alongside Lance Stroll and instead had to settle for a reserve and development role, but day two of testing in Barcelona saw the Pole post a time three-tenths quicker than the Russian.

And it is because of his new job that Kubica feels his times will be “irrelevant” when it comes to discussing his future with the team and whether he should have got the nod ahead of Sirotkin.
