Premier League Goals vs Assists - Visualized

KickDex plots all the goals and assists in the Premier League over the last three years, and look what they found!
The Goals - shown above, are really, really obvious - most (!) of them are between the penalty spot and the goal.  Again, pretty obvious, no?
But the assists?  Ah, now we're talking. As KickDex puts it

It is clear that to rack up the assists, a direct style isn’t the way to go. Only 14% of all assists come from long balls, and 29% from crosses (many of which are also classified as long balls). Over two thirds of all assists are short, precision passes made from just in front of the box and wide within the box. 

Mind you, this excludes corners (which, I suspect, would be kinda dark blue :-)
