Colombian has a contract at Porto until 2016.
Premier League outfit Manchester City are planning on going head to head with La Liga giants Real Madrid in the battle to sign in-demand FC Porto front man Jackson Martinez when the winter transfer window opens again in the new year, according to reports in Marca.
The prolific Colombia international has been attracting the attentions of whole host of big-name clubs from right across the Continent of late after the eye-catching form in front of goal that Martinez has been displaying for the Portuguese champions ever since the 27-year-old joined the club in July 2012.
Martinez joined Porto from Jaguares de Chiapas on a four-year deal for a transfer fee of just $11 million and in the intervening period, the Colombian has gone on to establish himself as one of the most deadly attackers currently plying their trade on the Continent.
In his first campaign at the Dragao, Martinez managed to find the back of the net on 34 occasions in total in just 43 matches in all competitions, including 26 strikes in only 30 league outings.
And already so far in this current season, the forward has netted 10 goals in 15 games, resulting in a battle for his services between the Blues and los Blancos come the turn of the year.
