Real Madrid Coach Julen Lopetegui has met with FC Porto captain Hector Herrera, according to a report in Diario AS.
Madrid are said to hold an interest in the central midfielder, whom new Coach Julen Lopetegui managed during his spell at Porto between 2014 and 2016.
Herrera joined the Portuguese champions from Pachuca in 2013 for €11m but has only one year remaining on his contract at the Estadio Dragao.
AS say the pair met at the hotel Yeatman, while a previous deal has not been possible with Porto holding out on a €40m fee for the midfielder.
The reports suggests the Mexican international wants to move to a bigger league after five seasons in Portugal, while he could replace Mateo Kovacic, currently on loan at Chelsea, permanently in the squad.
