Indeed, neither Ferrari driver used the fastest tyre available this weekend.
The Scuderia will be hoping the 1000th F1 race will be one that they can look back on as a turning point, while Red Bull will be going for back-to-back victories in the Chinese capital following Daniel Ricciardo's triumph previous year.
In just his second season in F1, it is widely assumed that it is just a matter of time until Leclerc tastes victory.
"I'm just focusing on trying to figure out what the hell is going on with my auto", the Formula One website quoted him as saying.

"For a four-time world champion to do so should be unthinkable".
Toto Wolff, Mercedes team principal, called Vettel's straight-line speed "frightening". "When you then can't do your final lap you know that the guys who are doing the lap have a chance of overtaking you". That left very little time on the clock for the drivers to complete the out lap and get their flying laps started before the session clock stopped, as cars go slow on their outlaws, especially the Mercedes cars who were at the head of the que going into the final lap.
If fans could have rigged the calendar, there would have been a number of circuits F1 supporters would have chosen ahead of Shanghai - Silverstone, Interlagos, Monaco, Albert Park just to name a few - to host the 1,000th Grand Prix.
