Tost was asked whether he thinks Pierre Gasly and Daniil Kvyat are his best driver pairing yet:

Yes, I would underline this, because as we know if we analyse both drivers. Daniil Kvyat has a fantastic natural speed. He won races, he won championships, just remember back in GP3. And Pierre Gasly as well, he won races, he won the GP2 championship and he drove last year in the second half of the season some fantastic races. Just remember his second place in Sao Paolo when he managed to keep Hamilton behind him one lap.
