Some folks just don't watch the game. It is bleeding obvious to anyone who does that Navas was 100% going for goal. Firstly, there was nobody in the box close to being positioned for a cross. Secondly, as soon as he hit it, you can see him watching the trajectory to see if it hits the target. And thirdly, his reaction to the goal was spontaneous. Not a "wow, I wasn't aiming for that, but I'll take it". But a "yes, I did it!" look of triumph. And a rather neat vault of the corner flag too :)
