For McLaren, the possibility that they will win the remaining races is quite big considering how the McLaren duo perform. But for Mercedes it will be quite difficult for them to win because besides having to fight McLaren, they also have to fight Ferrari, which has recently been quite aggressive in competing with RBR and McLaren.
Im McLaren fan for long time since Senna and Prost compete and always was even with dark times (new Honda era that works perfect for RBR).
To be honest cant remember when I last saw McLaren that good. New management and they are back on top where they should be.
Hope to see them win one race till season is over i sincerely hope they will do it.
