Juan Carlos Marino's agent has revealed that Newcastle should formally approach the Peru midfielder for a move to the Premier League.
The Magpies have reportedly approached the player but are yet to put an offer on the table.
"I understand that Marino will not return to Alianza in July," Gonzalez told 24 Horas Libre.
"I dismiss it because Juan Carlos is under contract with Hercules until June 31 and it exists a possibility that the Alicante club extend his stay, whereas other options exist from Spanish clubs and even Newcastle in England."
