Inter is backing out of the proposed move because of a backlash from fans, according to Goal Italy.
It emerged Monday that the Nerazzurri had agreed to allow the Colombia international to move to Turin in exchange for the Bianconeri's Montenegrin forward and an undisclosed sum of money.
However, Inter supporters reacted furiously to the proposed deal, inundating their club's official Twitter feed with messages of outrage, while the Curva Nord Milano issued the following statement:
"What kind of club policy is it to weaken an already limited squad in order to strengthen a rival? Guarin to Juve is not acceptable. A young and technically gifted player for an older one? All of this leaves us perplexed."
The fan reaction prompted the Nerazzurri to call off the transfer, Goal Italy reports, much to the fury of Juventus and Guarin.
In addition, Vucinic's agent, Alessandro Lucci, is trying to push through a straight transfer to Inter for his client, but the Bianconeri are now refusing to even entertain the idea of allowing the 30-year-old move to the Giuseppe Meazza without Guarin coming in the other direction.
However, the former Porto midfielder has not yet given up hope of forcing through a transfer to Turin, meaning this latest Italian soap opera may not be over yet.
