Williams Team Principal James Vowles has challenged Logan Sargeant to "earn" his future in F1.
The American rookie has shown flashes of promise in recent months after a difficult start to life in the sport, with his prospects not helped by teammate Alex Albon's stunning form in the sister car.
Whilst the Thai-Briton has amassed 15 points in 13 races, Sargeant remains scoreless and saw his best chance of a top 10 taken away by a hydraulic failure at the Dutch Grand Prix - triggering a crash into the barriers.
Sargeant's positon is one of four remaining up for grabs heading into next season and Vowles has outlined what he needs to continue in the seat.

Earn your place
Speaking to Sky Sports F1, Vowles explained: "Alex is here for the long term, I can tell you that already
"Where Logan is, he is on the right path to development, he has just got to step it up race on race.
"The comments I have given him are this: 'It is a meritocracy - you are not here just because we want you to be here, you have to earn your place. This is the pinnacle of motorsport and what I am asking of you is to follow the general guidance, follow the development path, keep moving forward relative to Alex and there is a place for you here with your name on it'.
"'Before then, there are points with your name on them. There was some available at Zandvoort if everything had gone perfectly, there are some available this weekend as well. Earn those'.
"That is how you earn your pathway into Formula 1."
