Atletico Madrid are making a late move for Porto striker Jackson Martinez.

Marca says Martínez seemed AC Milan-bound after spending some time holding out for Atlético, but a move to the Calderón could now be back on the cards.

The Colombian has stated loud and clearly from his country's Copa América camp that he hasn't made any definite decisions about his future yet.

Atlético are after a striker to lead the line and link up with Antoine Griezmann and Luciano Vietto, with Fernando Torres and Ángel Correa offering further options.

"We're close to bringing one in. He's good and expensive," Atleti sources say.

Jackson fits the bill. His release clause at Porto stands at €35 million, having been increased when he signed his latest contract, which runs until 2017.
