The agent of Colombian international Jackson Martinez insists that no deal has been agreed for the striker to join any club.
Reports in Portugal claim that Porto have won the race to sign the Jaguares striker - ahead of a number of other clubs including Liverpool.
Martinez and his agents have both previously claimed Liverpool were keen on securing his signature.
And now his agent Diego Cativa insists that the 25-year-old, one of the top-scorers in Mexican football, is yet to decide his future.
Asking whether the Porto deal was agreed, Cativa told Ojogo: "This is not true.
"Until the end of the season, there will be no developments on the future of Jackson."
Cativa also insisted that they are not holding talks with Porto.
