Furthermore, Leclerc has been outperformed by teammate Carlos Sainz so far this season, the Spanish driver winning in Australia, and claiming a podium in every race he has started.
Drivers such as Alonso and Lewis Hamilton, who will partner Leclerc next year at Ferrari, have demonstrated that F1 drivers can compete for longer.
Leclerc discussed Alonso’s contract extension with Tuttosport, and how the increasing age of F1 drivers leaves little space for younger drivers to advance into the sport.
“Fernando is one of the most talented drivers on the grid, he deserves his place in Formula One," Leclerc said.
"But there are also many young people who deserve a place and it's not easy to find a balance."
