The Bianconeri had looked set to offload their disposable striker to San Siro for the Colombian playmaker, but the Nerazzurri have backed out of talks
The Nerazzurri had seemingly agreed to bring Vucinic from Turin to San Siro on Monday, but fans reacted with outrage at the possibility of Colombian midfielder Guarin going in the other direction and the Milan-based club have done a U-turn.
"Internazionale decided not to continue negotiations with Juventus regarding the transfer of Fredy Guarin and Mirko Vucinic," the club announced on their official website.
"Club president Erick Thohir, having conferred with [honourary president] Massimo Moratti and the club's coaching team, did not feel that the necessary technical and financial conditions were in place to come to a satisfactory agreement.
"The president has already instructed the club's sporting directors to assess other transfer opportunities, with the aim of strengthening the team while respecting the parameters imposed by the Financial Fair Play rules."
The Serie A leaders seem baffled by Inter's decision to bail on talks over a swap deal but said they would refrain from commenting on the details of what happened until after their Coppa Italia clash with Roma on Tuesday.
"Juventus won't comment on Inter's press release," their website read not long after the Nerazzurri had called the deal off. "The club are focused on the cup game against Roma and then we'll explain this perplexing case."
Inter's withdrawal from the swap deal means that the Bianconeri must go back to the drawing board about farming out Vucinic in the winter transfer window.
Arsenal had been looking at loaning the Montenegro forward, but the Scudetto holders are believed to be keen on making his departure permanent.
Meanwhile, Guarin remains in Inter limbo as the Serie A giants ponder cashing in on the in-demand playmaker but unable to find a deal which works.
