Jaguares striker Jackson Martinez remains hopeful Liverpool will make a concrete offer.
Scouts from Anfield have reportedly watched him in action this season and he is available for around ã4m - but Porto are also in the hunt.
Martinez told Colombian newspaper Nuevo Estadio: "I am not in any advanced negotiations with Liverpool or Porto but I know they are personally interested.
"I have not spoken to anyone and that goes for my club and my agent.
"In the next few months thinks should be finalised."
