Barcelona are watching Jackson Martinez's exploits with Porto this season.

El Mundo Deportivo says Barca sports chief Andoni Zubizarreta has posted scouts to keep tabs on Martinez.

The 26 year-old Colombia international only moved to Porto in the summer, but has been a revelation at home and in Europe.

Asked about the Barca rumours, Martinez shrugged: "The truth is that I do not care. I'm with Porto, relaxed and happy."
