Chelsea were heavily linked with a move for the midfielder through December and into the new year, though ultimately turned their attention to bringing back former Blue Nemanja Matic.
Soon enough Juventus seized on the situation as the Colombian looked ripe for a switch, only for an agreed swap deal sending Mirko Vucinic the other way to be disastrously aborted by Nerazzurri president Erick Thohir.
Yet there was even more drama to behold before a torrid month would come to a close.
The Mail maintained that that Inter - temporarily freezing Guarin from the squad - had offered him up as a bargaining chip to finally conclude their protracted pursuit of Nani.
And now another twist has emerged - Guarin has been restored to the fold, and the Italian press insist he’s on his way to receiving fresh terms in Milan.
Reports last summer claimed that the Colombia international would be handed a new contract but a renewal never materialized after promises from former technical director Marco Branca to agent Marcelo Ferreyra.
Yet the much maligned transfer guru has since been sacked by the club hierarchy, with Calciomercato now claiming definitive contract talks will be held in his stead.
The Italian website maintains that initial contacts were positive, and another round of negotiations are set to take place in late February or early March.
Guarin - whose current deal expires in June 2016 - has reportedly demanded a base annual salary of €3m excluding performance bonuses running at least until 2017.
With incentives the deal would be expected to rise to around €3.2m per season, the same figure offered to the former Porto man by Juventus last month.
Guarin impressed in his second appearance since the January saga unfolded at the weekend against Fiorentina and his enduringly positive relationship with boss Walter Mazzarri is believed to be influencing the tentative decision to renew.
