Porto defender Nicolas Otamendi will join Valencia at the end of the season.
Porto have confirmed that Otamendi will join Valencia in the summer for a reported 12 million euros.
"After playing for a club like Porto - a huge, prestigious club - it is an honour to join a club like Valencia CF for this next stage of my career," he told Valencia's official website.
"Valencia CF are one of the most historic and attractive teams in Spain and in Europe, and I am very happy with this next step in my footballing life.
"I know that Argentinian players have been an important part of Valencia CF's history. To wear the same shirt as Mario Kempes, Roberto Ayala, Pablo Aimar and many more is a responsibility that I will take on with much joy and excitement."
