Jackson Martinez has indicated that he could leave Porto this summer amid continued interest from Liverpool and Tottenham Hotspur.

The Colombia international introduced himself to the European stage in emphatic fashion last season when he struck 26 league goals in just 30 starts; form that has seen him linked with a move away from the Estadio do Dragao.

Martinez's agent has previously played down the idea of the 26-year-old leaving Portugal following reports Tottenham were prepared to make a club record bid for the striker. But Martinez himself has indicated a summer move is a definite possibility in the summer months.

"We have to talk about my future," Martinez was quoted as saying in Portuguese publication Abola.

"There is nothing concrete but yes, there are options to leave this summer. I will contact Porto and then wait and see what might happen."

Both Brendan Rodgers and Andre-Villas-Boas face summers where they must address their differing concerns up front.

Liverpool are primed to lose their talismanic forward Luis Suarez, who struck 23 of the clubs 71 league goals despite missing the final five games through suspension, after he announced his decision to leave Anfield last month.

Daniel Sturridge's excellent form towards the end of last season combined with the club's pursuit of Henrikh Mkhitaryan who struck 25 league goals for Shakhtar Donetsk suggests the Reds are already planning for life after Suarez. But a move for Martinez, who bagged 34 in all competitions last season, could represent another ambitious move for the club.

Villas-Boas meanwhile is faced with the challenge of easing the goal scoring burden on Gareth Bale. The Welshman struck 21 in the Premier League while the manager's striking options of Jermain Defoe and Emmanuel Adebayor could only muster a paltry 16 between them.

Having missed out on coveted Champions League spot, Villas-Boas will be determined to address his squad's shortcomings which lie primarily in the striking department.

Porto meanwhile may have to brace themselves for another summer of rebuilding. Having already sold Joao Moutinho and James Rodriguez to Monaco, the club are also reportedly close to selling defender Nicolas Otamendi to Atletico Madrid.

Having signed Martinez for £7.7m last summer from Jaguares de Chiapas, the Portuguese giants would be expected to at the very least treble their investment if they were to cash in on the 26-year-old.
