According to gianlucadimarzio.com Inter Milans’s transfer market is starting to heat up as Piero Ausilio and agent Alessandro Lucci meet in order to discuss the availability of the young Colombian defender, Yerry Mina, who plays for the Brazilian side, Palmeiras. Inter only have two non-EU slots remaining, with one being occupied by Dalbert and now possibly Yerry Mina.

Yerry Mina, Inigo Martinez or Davidson Sanchez would be amazing CB signings
Probably I’d say we take Inago to save the non-EU slot for someone else (maybe douglass costa, or others). Inago more matured (26) and more experience in european football style rather than Yerry Minna. Davidson I heard is pretty expensive.
Costa is taking or has taken his medicals with RuBe.. He’s the second player we lost out on from them after Schick, and the third player we will lose out from the old ladri of Turin will probably be Bernardeschi 🙁
