Poli joined Inter from Sampdoria in a season-long loan last year, with Inter having the option to buy the midfielder for €5m after his loan ended.
The 22-year-old impressed during his stint on loan and head coach Andrea Stramaccioni was reportedly eager to bring him over to the Nerazzurri on a permanent basis.
However, according to reports from Sky Sport Italia, Poli pulled out from the deal after becoming increasingly frustrated with Inter dragging their feet over negotiations.
Poli's agent Giovanni Branchini also moved to confirm that his client would not be moving to Inter.
Speaking to Calciomercato.com, Branchini said: "In light of this on-going delay in negotiations no solution has been reached,"
"We note that obviously terms have failed to be agreed, otherwise the transfer would have happened by now."
"It was inappropriate to continue to wait for a solution and so we are now free from any moral commitment to Inter.
"Both Sampdoria and us were absolutely convinced that Andrea would have become an Inter player, so on Monday he will now re-join them [for pre-season training] and then evaluate what to do.
"We offer a heartfelt thank you to Inter who last year gave Poli an opportunity. Obviously now they have other priorities and we fully respect that."
Poli put in several eye-catching displays last season and the likes of Juventus, Milan and Napoli are reportedly keeping close tabs on the player.
