Ibrahima Mbaye’s agent Beppe Acardi spoke to Calcionews24.com regarding the future of his client who has just returned to Appiano to begin the preseason; “As it stands now he will go to Pinzolo and after that it is to the club to evaluate. We aren’t in a hurry, on the contrary.”

we should sell him to other club and put buy back price in the clause.
for example, sell him for $5 million and put buy back price for $6 million. Like what Madrid did for Carvajal. Thus even though the buy back price is slightly more expensive, but if he really become the next big thing, we could buy him back with a reasonable price. This is just my opinion.
He doesn’t lack quality to be Inter player but his playing time would be significantly reduced, interfering with his growth.
