Atletico Madrid have confirmed the signing of Colombian international striker Jackson Martinez.

The club announced the deal for the former Porto man on Wednesday afternoon. The 28-year-old has agreed a four-year contract with Atletico after the Spanish club reportedly met his €35 million (£25 million) release clause.

Atletico sporting director Jose Luis Perez Caminero said on the club’s website: “We are very pleased with the agreement, because Jackson Martinez is an extraordinary striker, able to rapidly solve any attacking play inside the box.”

Martinez, capped 38 times by his country, signed for Porto from Mexican club Chiapas in 2012 and has gone on to score 92 goals in 133 appearances, helping the club in the league title in 2013 and the Super Cup in 2012 and 2013. He scored 13 goals in 24 Champions League matches.
