Sebastian Vettel and Charles Leclerc are a “potentially explosive combination” who need to be handled with care by Ferrari, the team’s former technical director Ross Brawn says.

Brawn, now Formula One’s MD for motorsport, was the strategic mastermind through a golden era for the Italian team when Michael Schumacher racked up five championships in a row from 2000 to 2004, adding to two won with Benetton.

Vettel, 32, is a four-times world champion, but the German has been outperformed this season by 21-year-old rising star Charles Leclerc, who has taken six pole positions and two victories.

The pair stood out in last Sunday’s Russian Grand Prix for testy exchanges over the radio after Ferrari tried to swap their positions in a failed bid to engineer a one-two finish.

Mercedes won the race one-two instead, with five times champion Lewis Hamilton leading Valtteri Bottas, to end Ferrari’s run of three wins in a row.

“Ferrari has made a lot of progress in recent weeks but it still probably has to deal with a few internal issues in terms of the balance between its drivers,” Brawn said in a review of the weekend.

“It’s a potentially explosive combination and needs careful handling.”

Brawn said Vettel was still one of the finest drivers on the grid, despite a string of costly mistakes in recent seasons, while Leclerc was an “incredible talent” and “a star in the making”.

He said Ferrari principal Mattia Binotto, whose long career at Ferrari goes back to the Schumacher era, knew how to deal with the situation.

“Now the honour and obligation falls to him to make sure that mechanism that drives what can be healthy rivalry runs smoothly,” added Brawn.

With five races remaining, Leclerc is third overall in the championship and 107 points behind Hamilton. The Monegasque is 21 points clear of Vettel.
