Tottenham Hotspur are considering an approach in signing Arsenal and Chelsea striker target Jackson Martinez in the summer, according to the Metro.

The FC Porto star has been in fine form this season and has already scored 19 goals in 28 league appearances. His brilliant run for the Portuguese club has attracted the interest of clubs in England and Europe.

The Gunners and the west London club were linked with a move in signing the Colombian international at the end of the season. Martinez is weighing his options at Porto and is looking for a move away from his current employers.

The report claims the 27-year-old has set his sights on joining the Premier League club next season. The player's agent is in England to strike a deal with the clubs over a potential transfer.

It is believed that the White Hart Lane club has now taken the lead ahead of Arsenal and Chelsea in contacting Martinez's representative. The Spurs chairman Daniel Levy has held talks with the Colombian's agent over a summer switch to the north London club.

Tim Sherwood saw the Spurs suffer a defeat in the last league fixture, losing 2-0 to West Ham United at Upton Park on Sunday. The 45-year-old's future beyond this season remains uncertain and despite that Levy has already started preparing plans for the upcoming transfer window.

Earlier reports suggested that AS Roma had agreed on a deal in acquiring Martinez's services. However, the striker's representative has denied those claims and admitted that a decision over his client's future will be taken at the end of the season.

"The price remains the same? It's hard to say now. It depends on supply and demand and at this time Porto are focussed on other things," Martinez's agent William Lara explained.

"[Roma] is a big club, no doubt. Porto at this time has not yet initiated any contact about this matter. It has other matters to think about. The situation is critical, not the best. Porto are focused on this season finale, this situation will be evaluated later."
