Since Ozil's arrived Sanchez has had to play a lot deeper than usual, sort of like a CM. Think he's taking less free kicks too what with Ozil/Cazorla taking them instead so it's warranted his goal return has decreased. It's funny, they're our two biggest players yet I haven't seen any real form of chemistry between them so hard to play them together. Sanchez has scored the most amount of goals in CAM this season but it's highly doubtful Wenger will put him there over Cazorla or Ozil who is shunted to the left as it is.
I'm not really worried about Alexis's dip in form however, but I do hope he gets to stick with a position in the XI next year instead of being shunted all over the place. If Cazorla does leave this summer then I'd like Sanchez to get the 10' role over Ozil.
