Speaking to Zero Hora, Mario’s agent Jorge Machado said: “Anything can happen; you never know. But Porto want Mario. They really like his playing style.
“He is a 20-year-old athlete and highly valued. I do not know how much Gremio are asking for him, but it should not be a small figure.”
Mario could be seen as a potential replacement for Rolando, who has been linked with a move to the likes of Juventus and Roma.
