Diego Cativa, the agent of Jaguares striker Jackson Martinez, has insisted that his Colombian client has not agreed to join any club.
It had been suggested that the 25-year-old, who has also been linked with Liverpool, had agreed to join Porto, but these rumours have been dispelled.
"Until the end of the season, there will be no developments on the future of Jackson," Cativa told Ojogo.
Martinez has scored five goals in ten international caps.
