I wouldn't get too carried away about Welbeck just yet. He was playing against the Southampton second team Saturday and has looked awfully average against PL teams for an awfully long time. I'm afraid I'd need to see goals like those on a more consistent basis and against better teams before I got excited about him.

Perez, on the other hand, has looked very good this year. Perez Ozil and Walcott behind Sanchez seems like a rather good idea. Further back I have no idea mostly because I'm not convinced Wenger does either.
