Toro Rosso principal Franz Tost believes that new Red Bull recruit Daniil Kvyat has the ability to become one of Formula 1's best drivers.
The Russian racer was drafted in to replace Ferrari-bound Sebastian Vettel, despite having competed in the championship for only one season.
However, Tost is adamant that Kvyat deserves his chance with a top team, telling the official Toro Rosso website: "Daniil has done an excellent job being a rookie and has shown in this first year in F1 to be a very fast driver and to have the potential to become one of the top drivers.
"His strong motivation to learn and to achieve, his focus on how to improve his performance during the season, his great talent and his fighter attitude have given him the chance to step up quite quickly and to get the chance to move to RBR next year."
Toro Rosso have replaced Kvyat and Jean-Eric Vergne with youngsters Carlos Sainz Jr and Max Verstappen for 2015.
