The Bianconeri are furious that the Nerazzurri have performed a dramatic late u-turn on the proposed exchange
Inter have pulled the plug on a proposed swap deal with Juventus involving Fredy Guarin and Mirko Vucinic because of a backlash from fans - but it could yet be resurrected.
It emerged on 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, much to the fury of both Juventus and Guarin, who is desperate to no longer just leave San Siro but now also join the Italian champions.
In addition, Vucinic's agent, Alessandro Lucci, is trying to push through a straight transfer to Inter for his client, who is currently in Milan, 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, despite Inter's dramatic u-turn, neither player has yet given up hope of forcing through the swap deal and Juve director general admitted he remains hopeful of concluding a deal.
He said: "It's not closed but the deal can go in a good way."
All of the parties involved are set for further talks on the matter on Monday evening, with Vucinic still expected to undergo a medical with Inter, meaning this latest Italian soap opera could be set for one final twist.
