Martinez, 28, has scored an impressive 72 times in 107 appearances for Porto since signing from Mexican club Chiapas in the summer of 2012, with his goalscoring exploits attracting interest from a host of top European sides.
Both Arsenal and Chelsea were among the clubs linked to his signature this past summer before signing Danny Welbeck and Diego Costa, respectively, while the likes of Liverpool and Spurs are now understood to have entered the fold.
While Martinez is content with life at Porto for the moment, the Colombian international claims that a new challenge in another league is an option he would consider once the coming transfer window opens.
“Every player has his own aspirations. When the transfer window arrives I will be able to think about playing in other leagues," he said to Marca.
"Right now I am focused on following my path in this club, trying to do my best, and [a possible move] will come as a result of that."
Martinez’s comments should be tempered somewhat, however, after the prolific front man put pen to paper on a new deal to 2017 in August, with the terms including a release clause set at €35 million.
While that fee won’t be close to enough to ward off potential suitors, the clause won’t in fact take effect until the summer window, meaning Porto will be under no obligation to sell in the winter market.
Having scored 12 goals in 16 games so far this term, the Portuguese giants will no doubt want to hold onto their star man for as long as possible, but it remains possible that an enormous bid would just prove too good to turn down.
