Martinez confirms Atleti switch
Jackson Martinez has confirmed he will join Atletico Madrid from Porto and sign a four-year deal at the Vicente Calderon.
The future of the Colombia forward has been the subject of much speculation throughout the close-season.
Martinez initially looked set to join Milan, but Atleti duly emerged as favourites for his signature and the 28-year-old is now set to continue his career in Spain.
Speaking after his country's Copa America quarter-final defeat to Argentina, Martinez told reporters: "I can confirm I am going to Atletico.
"I am going there for four years, but I still don't know when I will be introduced.
"I have had great progression, always learning, always growing and now I'm going to Atletico, where I hope to help the team and continue to grow as a player."
A prolific scorer throughout his three-season stay with Porto, Martinez contributed 31 goals in all competitions last term.
