Torino president Urbano Cairo declared yesterday morning that the Livorno defender had signed terms with them.
But Knezevic's loan deal was confirmed by Juve in the afternoon and sports chief Alessio Secco rapped: "The player has signed one contract, ours, if there is another, it is wastepaper.
"The contract signed with us is the only one which has his signature and that of Livorno. From this point of view, it is official."
