The Colombia international will continue to be linked with a move to England if he continues his strong goascoring form this season.
Tottenham have consistently been linked with a move for a new striker over the last number of months, with an over-reliance on Harry Kane this season.
With Emmanuel Adebayor and Roberto Soldado failing to offer suitable support, Jackson Martinez has been linked with a White Hart Lane switch for some time.
The 28-year-old was back in action for Porto yesterday as the Primera Liga returned after the mid-season break and the South American scored again.
The Estadio do Dragao outfit romped home 5-1 against bottom team Gil Vicente, with Martinez scoring the fifth goal with this impressive finish on his left foot.
The strike makes it 12 goals in 15 starts this term for the Colombian this season, who has breached the 20-goal barrier in each of the last two league campaigns for Porto.
Porto representatives have claimed that Martinez is not for sale, however the Portuguese club have a track record of parting with their best players should the right price be agreed.
If Spurs want to land Martinez either in January or this summer, a new transfer record seems likely.
