Just a thought. If you guys get Prandelli next year, and Milan continue their interest in Canna- the last CD in the puzzle for next year might be Martin Laursen after all.
Prandelli used to coach him at Verona, and Laursen was really, really happy with him. After a good start- he hasn't been that assured in the Milan lineup, and with Maldini reportedly being a central defender next season- I don't think Laursen would have any qualms about returning to Parma id Canna goes rossoneri.
Another question is if you want him back though, as you would have a number of similar quality defenders. Might not be ideal not to have a "starting lineup".
Anyway- this rumour has been flying around on some of the less reliable Danish sites some time back, but I didn't really think about it, as I thought Canna would not be going to Milan. I suppose he might, so it's a scenario to consider.
Ciao.
