Blind would've been rightly lynched if Firmino had scored there at the end. Shocking laziness not to get back into the line there. De Gea saved his arse.
We're blessed to have him in goals, his composure in situations like that is incredible. I remember reading something about birds before, that they see things in a different frames per second to us and that's why they can move so quickly (leaving it to the last second to fly out of the way of your car etc) - They see everything in a slower motion.
I reckon Dave was born with the same thing.
