SALAS UNVEILED BY JUVE
Juve has also paid a cash adjustment, believed to be in the region of £8 million, in order to obtain the goalscoring talents of 'El Matador'.
The move had been hit by a late hitch, when the Chilean international demanded a payment from Lazio, but the matter was resolved and Salas can look forward to playing in black and white stripes next term.
"Marcello Lippi will decide if, and how much, I play," he told a press conference.
"Physically, I am ready but I still do not know my team-mates.
"Thanks to all those that have been close to me at Lazio these past few years, but now I am with Juve, and I want to think ahead to my new adventure.
"To arrive here is the dream of all players.
"It is pleasing the Bianconeri leaders wanted me, now I want to repay them."
So Salas exchanges Biancoceleste for Bianconeri, as Kovacevic joins Lazio as part of the deal, admitting he is willing to play for the next four seasons with the Roman outfit.
