I think Pessotto still has another good year,remember Ferrara two years ago?He was world class at 33.
Rosicky's defeding is average but with him there we'd be able to have Emerson concentrate on defending and allow Rosicky to take care of helping out the offense.With players like Blasi partnering him Emerson could go forward but did that to little effect this season so IMO we should have him play the role of our Gattuso.
As for the forwards,are you proposing that we sell one of the four without buying a replacement?IMO we will in all likelihood have four world class forwards next year,whether DP or Mutu goes or Gila or Cassano comes.
