He'll definitely win at least one and I personally think he's been made to look a lot more impressive by being paired with hopeless teammates who cannot get anywhere near him since Danny Ric saw which way the wind was blowing and moved to Renault.
The real fun is going to start when he's actually fighting for a title, he's been in the sport for nearly 6 years and never really had anything to lose. Even his braindead clash with Ocon in Brazil only cost him a win, he's never fought with a championship at stake and when he does have something to risk I expect he'll go full entitled asshole. If he does move to Mercedes I cannot see him and Jos doing much for team morale there either especially if they at least maintain the pretense of not having a number one driver. I did laugh at his comment about his engineer having a drink after he made the same comment last week because it was the most unsubtle way of showing how likeable he is.
It does make me laugh that people think this performance means he's now the fastest driver on the grid or that Hamilton is lucky because he has the fastest car when Alonso is a cautionary tale of how you can be fast but if you're a pain in the ass to work with no one is going to touch you. Hamilton not rushing to pass Leclerc because he was playing percentages isn't a sign that he's lost his fight, just that with a 30 point lead why take any risks.
