Paul Di Resta

When Felipe Massa pulled out of the Hungarian Grand Prix after FP3 concluded, Paul Di Resta - who hadn't raced in F1 since 2013 - was there in Budapest as a reporter for Sky Sports F1. He was asked by Williams to fill in the void left by Massa for further sessions in the weekend (Qualifying and Race).
He proved to be very impressive for someone who hasn't driven an actual F1 car in such a long time, and even managed to beat Marcus Ericsson's Sauber. In the race, he gave a good account of himself and no one other than perhaps Kimi Raikkonen - who was irritated by Di Resta for not following blue flags - had any complaints regarding his performance.
Just 10 laps before the end of the race, his Williams had a water-leak problem which put an end to a memorable weekend for Di Resta.
With his performance in Hungary, Di Resta has forced his way back into the shortlist of Williams for 2018 and he will hoping he makes the cut as he provided good performances before 2014 as well. His points tally was just shy of Nico Hulkenberg in 2012 and better than the experienced Sutil in 2013.
