The only luck was that SC entered just in time for Norris to take the lead after pitting. But in the remaining part of the race Norris drove really great.
After being on podium 15 times finally Norris also managed to win a race. By the way Verstappen made a mistake at a turn and the bollard he smashed caused a damage on his underfloor. This also affected Verstappen's pace after it. But I'm not saying this to underestimate Norris' victory of course.
Verstappen is only human and he can mistakes sometimes
Norris is one of the youngest top F1 drivers being 25 years old, so this is going to be very big motivation for him to continue with good results.
83 points is not far behind Leclerc and Perez and I am expecting him to try and take one of top positions in the end of season, But Sainz is there also.
