Fair point, I'm sure you are correct. We aren't exactly the best at attacking the ball at set plays anyway so the delivery is redundant much of the time.
Van Persie is good at lashing it in with pace and hoping for the best and occasionally it works, but a lot of the time it is cleared at the near post as he has been hitting corners and free kicks very flat for some time now. I cant remember the last time he got some real whip on a set piece.
Arteta on the other hand has always seemed excellent at picking out Everton's main attacking threats at set pieces rather then simply putting it into an area with as much pace as possible like Van Persie, but by getting some real shape on his crosses and knowing where his team mates will attack.
I have no doubt we will have been practicing Mertesacker/Djourou/Chamakh/Koscileny/Vermaelen attacking Arteta's crosses the last few training sessions, with Van Persie hanging around the edge of the box I'd imagine, as Arteta has the ability to pick out such a ball aswell.
If we cant cause some problems at set pieces today against a relatively small Swansea team then we really need to buck up our short corner routine as crossing will just be a waste considering the sheer amount of corners we win.
