If you look at the player stable that AC Milan has as well as its history of achievements. I totally agree with the ranking as numbero uno. I feel AC Milan is the most complete team in Europe at this time, and their dominance will be felt this year as well.
Considering I'm still learning about UEFA and how the system completely works, I'm not a total AC Milan fan. I don't think I will be. I'm more of a follower right now - such as Manchester United for example.
But still, all teams in every sport have their time - and right now it's AC Milan's time.
