Valencia sign Otamendi from Porto

Argentinian international Nicolas Otamendi joined Spanish club Valencia from Portuguese champions FC Porto for €12m, the selling club announced. The 25-year-old central defender, capped 16 times, could eventually cost Valencia up to €15m with add-ons. Otamendi has been at Porto since signing from Argentinian side Velez Sarsfield in 2010. Valencia are way off the pace for a place in either the UEFA Europa League or UEFA Champions League for next season, currently lying eighth on 28 points, 29 adrift of leaders Atletico Madrid. Porto are third in their title race, four points behind leaders Benfica, and also went out of the Champions League in the group stage. Source: FIFA.com
