Marino managed Sanchez during his time at Zebrette, and the coach thinks that of the all the teams the Barcelona forward has been linked to, it is Inter who would best fit the Chilean's versatile style of play.
"Alexis Sanchez is an exceptional player, I think he'd do really well at Inter," he told reporters.
"He can play in a lot of formations. He can be the second striker in a 4-4-2 – or even as the wide midfielder in that shape.
"He can play as the wide attacker in a 4-3-3 or the second striker in a 3-5-2. In a 4-2-3-1, he can be used in all three roles behind the striker."
Along with the Nerazzurri, the 24-year-old has been linked with a move to Juventus, Arsenal and Liverpool in recent months.
