It may be a loan deal, since no website has mentioned a transfer fee.
I'm not happy with Capello. Of course I can't blame him for Tacchinardi being fifth choice and wanting to leave, but this is partly caused by signing Giannichiedda. While the latter is a better player Tacchinardi has been with us for 10 years.
In my opinion Capello only thinks in the short term. We may win everything next year but we will have a serious problem in three years with Nedved, Emerson, Vieira, Camoranesi, Cannavaro and Thuram all being 32+. One of the main reasons why I started supporting Juventus was that players and club were so loyal to each other. Two years ago we had Del Piero, Tacchinardi, Ferrara, Conte, Pessotto, Birindelli, Montero, Iuliano etc. who were all at the club for ages. Nowadays we don't sign players in the hope that they will become great and stay with the club for 10 years, such as we did with Zambrotta. Instead we sign players like Emerson and Vieira who only join because they are paid a lot and likely to win trophies. Of course this is good, but you need to sign players who will stay at Juventus longer then 3 years. Else you will regret it in the long term.
