Robert Kubica's Formula One return will finally happen in 2019 but the Pole has been very honest about his situation. As popular as he is with fans, Kubica acknowledged that it is easy to doubt his ability ahead of a return to F1 racing after his rally accident.

After eight years away from Formula One following a horrific accident whilst rallying, Kubica will make his return to the sport in Melbourne with Williams.

Although he tested for both Williams and Renault ahead of his comeback, he admitted that he could understand doubts people have over his competitiveness adding that if he was a team principal, he too would be cautious.

"If I would be a team principal I would also have doubts," Kubica is quoted by Crash.net.

"This year has been very useful because at the first meeting, I remember, I said 'If you have any doubt, we shouldn't be doing it, because in difficult times it's easy to point the finger on my arm - I want to make sure that you are sure that I can do it'.

"First of all I have to be sure that I can do it, that's why I'm here, but second of all the team has to be convinced that I'm able to do a job."

"If I think I will not be able to drive competitively fast I would not be here," he continued.

"This is a normal way of thinking, that people see my limitations and they ask how it's possible that I do it.

"I know that it's hard to believe but Williams has seen it this year and I have seen it (for) the last 16 or 18 months, since I first tested an older Renault F1 car in Valencia that I can do it.”
