Ferrari legend Ross Brawn has warned his former team it will need to carefully manage the dynamic between Sebastian Vettel and Charles Leclerc to prevent an all-out civil war.
The pair were embroiled in controversy at the Russian Grand Prix. At the start, Vettel had got past Lewis Hamilton and used the slipstream of Leclerc to pass his teammate into Turn 2.
This appeared to have been part of a pre-race agreement to neutralise the threat of Hamilton, with part of the deal being that Vettel would give the lead back to Leclerc later in the race.
