Charles Leclerc declared his Ferrari team is "making our lives way too difficult" as he bemoaned another blunder.
He only managed to qualifying 11th for the Canadian Grand Prix, failing to make it through to Q3. And that was because he stayed on intermediate tyres while the track was drying out.
Most others had switched to slicks and were faster as a result. Leclerc was one of only three drivers who remained on the intermediates, along with Sergio Perez and Lewis Hamilton.
