Verstappen said though it was a fine margin in the end of the Sprint so he knows very well he has a lot of chances to win the race and he will take it slow in the beginning,it is exactly here that the guys in front especially Leclerc should start pulling away.
I'm afraid I don't think Leclerc can keep some good amount of time gap until Verstappen comes right behind him. I even doubt Leclerc about keeping his lead until then. Because Ferrari are still having problems when it comes to races. They are one of the bests when it comes to qualifying performance but they can't have a good pace in a long-running format.
Norris was nearly hunting down Leclerc in the sprint race as you can remember. McLaren and Mercedes both seem to have better pace then Ferrari considering the sprint race performances. I just hope that Leclerc can manage to cling to podium at the end of the race.
