I do get the feeling from Wenger's comments about "one day I'll write it all in a book", that he's actually telling the board, "put up, or shut up".
I think he wants a few quid to spend. I think he wanted business done earlier last season. And I think he'll get his wish this year.
That said, it remains to be seen whether he'll be clinical enough. If he's ruthless, and does what each and every one of us believe is right for the team (let's leave aside him resigning), then there's no reason to suggest we can't challenge.
I'm not sure he's good enough to win us the title anymore. That said, I've not seen him have a proper spending spree....ever...
