With the budget AC Milan has its going to be difficult to make any high profile signing this summer.
They can still play well and perform better with what they have or with whatever they can get, but that's a very big gamble. Now, not only are the focused on players to sign, but they are also focusing on a technical director to hire.
Personally, I believe a good technical director will make good signing. So if the person taking over is not very good at his job it will be a very big issue for Milan.
