Charles Leclerc is at risk of another costly engine failure at the French Grand Prix, Ferrari have admitted.
The Monegasque has already lost dozens of points this year thanks to power unit issues. He looked set to stroll to victory in Spain before his engine failed, before the exact same thing happened while he was in the lead at the Azerbaijan Grand Prix.
Team-mate Carlos Sainz has also been affected by the problem. His latest power unit struggle came last time out in Austria, when he was denied what looked set to be a second-placed finish when the engine caused his car to quickly catch fire.
