Please elaborate? Leclerc was comfortable in 3rd place. And MB could not even pass the tortoise Sainz?
This is the 1st race of the season and all cars does not work great on all tracks.
As for Binotto, anything unreliable at this stage is still his doing, Fred is there for a short while, he might have had a few changes in staff and decisions, but no ways anything on the car has his influence. These cars and their development are planned long ahead, so the soonest Fred will have any influence on performance of car will maybe be late in this season, but probably only next season.
