2016 world Champion Nico Rosberg insists Charles Leclerc’s arrival at Ferrari will be one of the most fascinating aspects of the 2019 season.
“I’ll switch on the TV just to see the fight between the two Ferrari guys,” German Rosberg told Italy’s Autosprint.
“Leclerc is so strong. And Vettel is coming out of a difficult year. He will have to remain very focused and give his all if he wants to remain the Ferrari leader.
“Leclerc is not Raikkonen,” Rosberg added. “It puts a lot of pressure on him.”
Rosberg thinks the biggest problem for Vettel could be his inability to change his approach in order to fend off the Leclerc challenge.
“If you have too much confidence in your abilities, as he does sometimes, you’re not ready to change that attitude,” he said. “That’s what I suspect of him. That he is not capable of modifying his approach.”
