Ac Milan brought him quality players both in midfield and in attack but they failed to do so in the defence. This is the main reason why I can rate their transfer done a one hundred percent. Though, they have players who can thrive until they go get a new defender when the January transfer window comes. I can't say completely where they would end up but best believe, first 4 has got to be their set target if I'm not mistaken. 
And what Ac Milan is doing is obviously what almost all the club's are doing now because they have found out the importance of having quality players because if you have quality players that will determine the condition of which your club will find its self. And this is one of the reasons why am actually buying the idea of improving as a club if not that club will be left behind.
Because if you look at It Ac Milan is part of the club's that have good reputation and they lost it due to proper maintenance of the club, because consistency in bringing in new players also have its own way of affecting the club so we should ask for a proper entertainment when ever they are playing. Because the whole structure of the team have to be active before they can archive there own goal so there is always reasons for proper structuring.
