While checking something on acmilan.com I just clicked on Milan Team and what I thought was that we were missing the creativity, and the super-sub that we used to have.
Maybe most of you would say that you miss Sheva because we had kind of problems with scoring this season, or maybe Stam coz we had problems and injuries in defence (although we have one of the best defences in Europe, according to how many goals we have conceded), I still think that the one that we are missing the most is Rui.
He had creativity, vision, experience, technique, quality... he was great. Moreover, he could play mostly everywhere in midfield. He was always there when Kaka, Seedorf or Pirlo were missing, and the only one that he couldn't replace was Gattuso.
Now, Gourcuff can be his replacment in a way, but he will need some years till he can be like Rui.
So, I think that Rui is the one that we are missing the most, and the one that would improve Milan's performances this season.
