Robert Kubica announced he’ll be depaerting Williams at the end of the 2019 season, putting an end to one of the greatest comeback stories in the history of the sport.

“I have taken the decision that I will not continue more with Williams after this year,” Kubica told Formula1.com. “The decision opens a bit the opportunities for me for the future in different scenarios and now I will evaluate what is possible.”

When asked if he would have like to have stayed in F1, Kubica answered: “Of course, my answer will be yes, but not [at any] cost, and I think I have to first of all do what will bring me back a bit of joy of racing.”

“This season has been very tough from a performance point of view, but it’s been also very demanding. Being back in Formula 1 after a long time is not easy, and especially when you’re in a difficult situation like we are. But still, nevertheless, I have to thank the team for the opportunity and we’ll see what the future will bring,” he added.

This most likely marks the end of the Pole’s F1 career, who was out-qualified by his teammate George Russel at each of the 14 races so far this year while Williams is struggling with its performance.

“I would like to thank Robert for his hard work and respect his decision to leave the team at the end of the 2019 season. Robert has been an important member of the team in both his role as Reserve & Development Driver, and subsequently as one of our Race Drivers in 2019. We thank him for his continued efforts throughout what has been a challenging couple of seasons and wish him well in his future endeavours,” said Williams Deputy Team Principal Claire Williams in a statement.

Kubica is reportedly in talks with Audi about him moving to DTM and Williams is considering filling his seat with either their test driver Nicholas Latifi or Nico Hulkenberg.
