Arsenal have reignited their interest in Colombia international Jackson Martinez, according to the striker's agent.

The Porto star is set to have a key role to play for his country in this summer's World Cup in the absence of Radamel Falcao after another goal-laden campaign in the Portuguese top flight.

Martinez, 27, has been persistently linked with a move away from the Portuguese giants but could be on his way out in the coming months. Serie A duo Napoli and Roma were thought to be keen on securing his services, but his agent now believes the Gunners, along with Valencia, are now favourites to land his client.

"In Italy we have had very little contact, but for sure there have not been any offers from Roma," Martinez's Italian representative Peppino Tirri told Calcio Mercato.

"There are, instead, opportunities abroad, Arsenal and Valencia in particular are very interested in Jackson Martinez."

After much of the goal scoring onus was left on the shoulders of Oivier Giroud last season, Arsene Wenger has made the recruitment of other forward options a priority this summer.

The Gunners have already made moves to resign Carlos Vela from Real Sociedad, having informed the La Liga club of their intentions to activate a buyback clause inserted in the Mexican's contract when he left north London two years ago. The deal allows the Premier League side to sign the forward for a fee of just £3.2m, a fraction of his current market value after a sparkling campaign in Spain last season.

The Gunners also remain linked with Real Madrid starlet Alvaro Morata who will be allowed to leave the club this summer after playing a peripheral role in the first team squad last season. Former Manchester City star Mario Balotelli and Loic Remy are also in the frame for moves to north London.
