5- British GP:
Silverstone hosted an eventful race this year, with one of the best battles in many years between Charles Leclerc and Max Verstappen. What it was remarkable for, championship-wise, though was Hamilton’s hunger.
Having been stripped of pole position on Saturday by Valtteri Bottas by just 0.006 seconds, Lewis showed the world -but most importantly his team mate- his strength. Starving straight away for the lead, the future six time world champion put on a fierce battle with Bottas, who managed to hold him off. When Valtteri was called in for the scheduled second stop, Hamilton decided to disobey team orders and extend his tyre life to the checkered flag. Not happy enough with the incoming win, the british driver pulled out of the hat an astonishing fastest lap of the race on the very last lap on massively worn rubber. With a 39 point lead in the championship and such a superior performance, Hamilton had already put one hand on the title.

4- Singapour GP:
After two pole positions converted in back-to-back wins by Charles Leclerc, Ferrari managed once again to rise their heads. Still, both Spa and Monza were tracks well-known for suiting the car’s project, while Singapour –a twisty and narrow street circuit- was next on the calendar. Apparently out of nowhere, instead, the Scuderia managed to secure a front row lock up on Saturday and a one-two finish on race day. This meant that, alongside Red Bull, now there was officially a second power able to give Mercedes big headaches.

3- Italian GP qualifyings:
The exact moment everything started falling apart inside Ferrari. Having got on provisional pole, also thanks to Vettel’s slipstream, Charles Leclerc was supposed to tow his german team mate on the final run of Q3 at Monza. The Monegasque instead decided to keep Sebastian behind at a very slow pace. This meant Vettel (and basically everyone else) couldn’t complete his out-lap in time and Leclerc took one of the weirdest front starts in history. The two drivers, according to paddock rumors, spent more than one hour locked in a room with team principal Mattia Binotto but nothing was fixed: Singapour, Russia and Brazil came afterwards and added even more spice to the red rivalry. That’s something Ferrari has to keep well in mind for next season as well.

2- Austrian GP:
For the second time in his debut season for Ferrari, Charles Leclerc topped the qualifying session at Spielberg. Just as in Bahrain though, the Monegasque saw himself robbed of victory in the closing stages of the race. If an engine issue had prevented him from winning in Bahrain, this time it was a hard wheel-bang from Max Verstappen to force him out of the top step of the podium. That overtake made him completely change his mindset, as we have analyzed in depth in the article linked below.

1- Canadian GP:
High tension and drama in Montreal: Sebastian Vettel, first on the finish line, classified second due to a five seconds time penalty for having ran Hamilton out of road. Public opinion and medias outraged, forcing the FIA and the stewards to adopt a more forgiving judgement on race manouvers. Consequence of this change were both Verstappen’s win in Austria and Leclec’s triumph at Monza. If Canada never happened, the Dutchman would have recived a penalty for the attack on Leclerc and the Ferrari driver would have lost the lead in Italy for having put Hamilton on the grass at Della Roggia chicane.
