Yes but Samuel has won a Scudetto with Roma, which is, I hate to say it as I remember Totti's words, worth like 3 Scudetto's with Juventus or Milan. Samuel is a world class centre back, proven and experienced in ALL competitions. So Cannavaro who has failed at 2 different clubs now is also a failure, bad defender, what is he/they? They are still world class players, you don't loose quality like that but you gotta gain it.
Oh and Barzagli is yet to fail? Are you freaking kidding me? What has he achieved anyway? Over a hundred goals in his net for 2 seasons?
And your opinion on EPL is a complete stereotype and is complete nonsense. Ferdinand and Vidic would walk into any defense at the world this moment, not to mention John Terry for example. There are good defenders outside of Serie A.
I'm sorry but it's a fair description, he is unproven in every single sense of the word. Barza=potential, that's all and potential is not always fullfilled.
Yes, spending reasonable money on proven players for our weakest department is what we should be doing. We are not in a position to take a gamble on anyone.
And please don't play that WC card, Italy would have been champions with or without him, he wasn't exactly crucial.
