Now , time to make quick predictions because it seems RedBull came here with huge upgrades on their car and maybe it's finally time for Perez to score vital points for his team ? Because if he won't do this , I'm afraid that McLaren will snatch constructor championship from Redbull by the end of the season. However , I do see Max winning both pole and the race from Sunday so that should still be a great sign for him and Redbull.
