FC Porto have strengthened their attacking options for the forthcoming season with the signing of Atletico Madrid striker Adrian.
The Portuguese club announced the signing on their official Twitter account though no details about the transfer fee or the length of contract signed by Adrian have been released.
With the club set to depart for a pre-season training camp in Holland, the media team released a tweet which read: "The team is now travelling for the Netherlands and there's a new player on the squad: @adrian7oficial! Welcome!"
The striker becomes the second man to swap the Spanish capital for northern Portugal this summer following Oliver Torres' season-long loan move to the Estadio do Dragao.
The duo will be joined at the club by former Spanish youth team coach Julen Lopetegui who was named Porto manager earlier this season.
Lopetegui is inexperienced in club management, but his early signings suggest his knowledge of the Spanish league will come in handy as Porto look to strengthen a squad who could only finish third in last season's Primeira Liga.
Adrian's move away from Atletico comes in the wake of the La Liga champions securing the signing of Bayern Munich striker Mario Mandzukic.
The move is just another turn in a transfer merry-go-round which has seen a host of top European clubs trade strikers.
It all started when Robert Lewandowski agreed to join Bayern Munich at the end of his Borussia Dortmund deal, meaning Mandzukic became available for Atletico.
The Spanish side were in need of a striker having allowed Diego Costa to move to Chelsea, while Adrian's switch to Porto could allow Jackson Martinez to move to a number of potential suitors.
The 26-year-old will be turning out for his sixth professional club having had spells at Deportivo, Malaga, Alaves and Oviedo before settling at the Vicente Calderon.
It was at Atletico where he enjoyed the best football of his career, and in 2012 his club form earned him a call-up to the Spanish national team.
Adrian scored on debut in a friendly against Serbia but has made just one more appearance for Vicente del Bosque's side since.
Though he wasn't exactly prolific during his three years in Madrid, he did score some crucial goals, including Atletico's opener in their 3-1 Champions League semi-final victory over Chelsea last season.
Adrian would have to settle for a runners up medal as Real Madrid sealed a tenth Champions League title but he would finish the season as a La Liga winner.
Having joined Porto he'll be hoping to secure a second consecutive league title as the Portuguese outfit look to bounce back after a disappointing campaign last time out.
