Where do we need to improve?

Assuming that our best line-up at the moment is;

Dida
Cafu Nesta Stam Maldini
Gattuso Pirlo Seedorf

Kaka

Sheva Crespo

Where do people think we should improve for next season? Looking at that team the only players I would really consider replacing would be Stam, Seedorf and Crespo.

Before people start having a go, I personally wouldn't replace Crespo as I think he's be brilliant this season, especially in the CL final, although if we do sign Gilardino I wonder what his role will be?

I would also have reservations about replacing Stam, although If we signed someone like Chivu it may be worth while.

As for Seedorf, I haven't really rated him this season, and would have liked to see Dhorasoo given a longer run, although thats just my opinion.

What do others think???
