Red Bull team principal Christian Horner believes his former driver Sebastian Vettel could be pushed to a new level by the arrival of Charles Leclerc.
But, Horner predicts a much sterner test for the German from Leclerc, and believes he may force Vettel to dig deeper than ever before.
“Charles is a really exciting talent,” Horner told Autosport.
“For the sport it’s great to see.
“Sebastian’s now 31, you’ve got these youngsters coming through starting to put pressure on the established guys.
“From a sport point of view, it’s fascinating.
“He [Vettel] had Kimi pretty easily covered. He might have to work a bit harder with Charles but he may now find a new level.
“So it might in turn be good for him to be pushed even harder.”
Ferrari are set to increase their Formula 1 budget this year, and have appointed Mattia Binotto as team boss in place of Maurizio Arrivabene, as well as adding ex-Formula One drivers Brendon Hartley and Pascal Wehrlein in simulator roles.
Horner, however, believes former Ferrari engine programme leader Binotto, could be stretched too far after his latest promotion from technical chief to team principal.
“It’s a big job for Mattia because you can’t do both roles,” he explained.
“You’re either technical director or team principal and I think he’s probably got that difficult scenario where he’s running between offices at the moment.
“Both are enormous jobs in their own right so it’s going to be a process of evolution.
“They’ve made their changes for whatever reason, they’ve decided upon the fifth team principal that I’ve sat opposite to in Ferrari in my time at Red Bull.
“And with every management change there’s a change in culture and approach, and that takes time.”
