What are Ibrahimovic's plans for next season? The man can no longer play entire 90-minute matches, would AC Milan still use him as a substitute? The years are now beginning to count double for the Swede. Although, without him AC Milan would not have become champions I think. He has something with charisma that makes the whole team much stronger mentally. And his experience is also used optimally. Zlatan is a real enthusiast, he doesn't have to do it for the money.
Firstly, he has to recover from the operation and I heard that the recovery will take a long time and by the beginning of the season he will not have time to do it. Secondly, he agrees to stay in Milan on any salary terms, so next year he will be at the club. How much game practice he gets depends on his health, I think.
The collapse of Serie A started with Lazio, Parma, Fiorentina after their presidents over paid for transfer and salary. Then debt, loan call, bankruptcy come and best players leave Serie A to other leagues. Calciopoli makes it worse.
I think Serie A is in a slow recovery and their system for youth players is not good as Bundesliga. It will constrains their recovery in next few years. If you are not rich financially, you must have good home-grown players. Serie A clubs are lack both of these things.
Serie A as a business shows very weak results, so in fact it continues to lag behind the leader (the Premier League) and apparently from other developing leagues.
