You're definitely right, their legs did get tangled - I'm not suggesting there was no contact and he dived, what happened is Vardy deliberately ran across the defender so that they would collide. He wasn't running that way to try and get the ball etc, he deliberately caused the collision. That's...
Agreed.
I think he offers a lot more than goals, he's an outlet for the team and holds the ball up well. I don't know why you singled out winning goals, the others are important to aren't they?
Indeed.
