Real Madrid are reportedly considering a move for Porto midfielder Hector Herrera next summer, with the player potentially available on a free transfer.
According to Marco Ruiz of AS, the Mexico international will not pen an extension with the Portuguese side and is set to join a bigger club soon. If Herrera doesn't sign a new deal, then he will be able to negotiate with teams from January regarding a pre-contract.
"He wants to leave Portugal for a bigger league and Real Madrid could be in the running," continued the report. "Inter Milan tried to sign him this summer but Porto president Pinto da Costa made it hard for the Serie A side and would not back down from the €40 million (£36 million) release clause.
