The Argentinian international was thought to be on his way to the Nerazzurri but negotiations over a loyalty payment have put the deal in jeopardy.
Kily Gonzalez has already agreed a deal with the Serie A side that will see him take a wage cut and the player is now demanding Valencia pay him the amount he will lose out on if they want him to complete the transfer.
The Spanish side are set to have a final meeting with the player's agent in an attempt to iron out the problem.
Inter captain Javier Zanetti feels that the capture of Kily Gonzalez would be an important signing ahead of the new season.
"We know his value and he would be an important pawn for us, he would certainly help our squad."
