Martinez, 27, arrived in Portugal back in 2012 from Chiapas having impressed for the Mexican side, hitting 35 goals in 69 games, establishing himself in the Colombia national team as well. His first season with Porto was immensely impressive, hitting 31 in 40 goals, and he has followed that up with 23 goals in 40 games this season, and that sensational goalscoring record has attracted the interest of a number of sides.
Arsenal are the side who have been most heavily linked with a move for Martinez, as Arsene Wenger looks to provide some support for Olivier Giroud. Nicklas Bendtner will leave the club at the end of the season and youngster Yaya Sanogo isn't ready to contribute heavily yet, and the lack of support for Giroud is a large part of Arsenal's recent collapse in the Premier League title race.
So it will serve as a boost to Wenger that Martinez, a reported £30m target of the Gunners, has spoken about his future in the Portuguese press, suggesting that there could be a move away from the club after the World Cup, where he is expected to feature heavily for Colombia, particularly if Falcao fails to recover from his knee injury in time.
“I’ve not renewed with the club. It’s something that we have been discussing during the season," Martinez said. “As for my departure, I have a contract with FC Porto. After the World Cup, many things can happen but I am focused on continuing to do an excellent job for Porto and the rest will come with time.”
With such an impressive record in Portugal, it's easy to see why Wenger is interested in bringing Martinez to North London, though the speculated £30m fee could be too rich for the Frenchman's blood - after all, he's hardly renowned for splashing out large amounts of money for players.
