Robert Kubica's Formula 1 return might be in jeopardy with Williams after just five races.

The Pole completed a fairytale comeback eight years after his rally accident left him with serious arm injuries and having completed numerous tests with Renault and Williams since 2017.

However, his performances have been disappointing as he is yet to beat teammate George Russell in their private battle at the back of the grid.

Kubica has blamed his pace on what he believed to be differences between his chassis and the Briton, however, when they swapped cars in Barcelona, the 20-year-old was still faster.

Now, Le Journal de Montreal has reported Nicholas Latifi, who is also a Williams reserve, could be getting ready to step into the second seat in the coming races.

The current F2 series leader is driving both days at this week's test in Spain and according to the Canadian publication: “Kubica reportedly had a clause in his contract stating that he could be replaced during the season.”
