The point is that there isn't enough money to do so. The names that have been mentioned are or will be hot names in the market. There are going to be other clubs going after them.I'm fairly confident that Wenger very well knows that this club will implode if he isn't extremely aggressive this summer, a large number besides Özil and Alexis have to be replaced. What is questionable though at this moment is which rate of talent he is able to lure over to this club.
We aren't going to get market value for Özil and Sanchez either simply because they have 12 months left on their contracts.
Realistically? Maybe 1 WC player (if at all) and a bunch of average players is the likelihood.
