That is the newest in a sequence of expensive errors Leclerc and his race engineer have made in unpredictable moist climate situations. It’s the first since Bryan Bozzi changed Xavier Marcos Padros because the voice in Leclerc’s ear.

In Sochi three years in the past Leclerc, having made up 15 locations to run fourth when rain arrived, dedicated the identical error as race chief Lando Norris by staying out on slicks tyres too lengthy when rain arrived. That duff name left him out of the factors on the finish of the race, whereas Sainz got here in for intermediates earlier and bagged a podium end because of this.

The next 12 months Leclerc threw away a possible win in Monaco with an pointless tyre change on a slowly drying observe.
