Atletico Madrid will confirm the double signing of FC Porto duo Hector Herrera (pictured) and Alex Telles this summer, according to multiple reports.
Portuguese outlet A Bola led with the story on Monday morning, following on from a report last week in Marca that both players had agreed a move to the Spanish capital.
Telles has also been linked with moves to Real Madrid and Juventus while Porto had been adopting a stance that they will not sell the defender for less than his €40m release clause, fresh reports say a €30m fee will be agreed.
Atleti need to strengthen their left-back position with Filipe Luis out of contract this summer and Lucas Hernandez already having agreed a move to Bayern Munich.
The 26-year-old has previously enjoyed spells at Inter and Galatasaray and last season helped Porto to their first league title since 2013.
Porto captain Herrera joined the Portuguese champions from Pachuca in 2013 for €11m but has only three months remaining on his contract at the Estadio Dragao.
Italian club Inter have also been linked to the Mexican international while Real Madrid were said to be interested in a deal when Julen Lopetegui – who coached him at Porto – was boss earlier this season.
