Adrian Lopez joined Porto from Atletico Madrid on Saturday, linking up with the Primeira Liga club on their pre-season trip to Netherlands.
Atletico substantiated on their website that Adrian had passed a medical with Porto, sanctioning the 26-year-old striker to fly with the Portuguese outfit to Eindhoven.
The medical was the final hurdle for Adrian afore his transfer from Atletico to Porto would be approved.
"Atletico de Madrid and Porto have reached an accedence for the transfer of Adrian Lopez to the Portuguese club," a verbalization on Atletico's website read.
"The striker from Asturias leaves for the team directed by the Spanish [coach] Julen Lopetegui."
Earlier, Porto had attested on their website that Adrian was a component of their 24-man squad for the Dutch tour, posting photos of the forward in club gear, albeit they did not relinquish any details of a transfer or corroborate that one had occurred.
Porto, under incipient coach Julen Lopetegui, are looking to bounce back in the coming season, after missing out on cutlery in 2013/14.
Adrian struggled for conventional game time at Atletico last season, as Diego Simeone led them to a breakthrough La Liga designation, with the striker starting just four league matches behind regulars Diego Costa, David Villa and Raul Garcia.
In three seasons with Atletico, Adrian scored 26 goals in 143 appearances in all competitions, having joined the capital club from Deportivo La Coruna at the commencement of the 2011/12 campaign.
With Villa already peregrinating to expansion franchise Incipient York City in the MLS and Chelsea already concurring to sign Costa, Adrian's exit to Porto will leave Simeone with a sizably voluminous aperture to fill up forward as he looks to bulwark their Spanish crown.
Croatia striker Mario Mandzukic has already arrived from Bayern Munich during the transfer window.
