Chelsea have been put on red alert following the news talks over a new contract for Jackson Martinez at Porto have broken down, according to talkSPORT.
Jose Mourinho has been heavily tipped to sign a new striker in January, with Fernando Torres, Samuel Eto’o and Demba Ba managing just five Premier League goals between them so far this season.
Mourinho has sent scouts to watch Martinez in action for his former club several times this season, and believes the Colombian could be the man to provide the goals missing from the Blues attack.
Porto remain desperate to hang onto Martinez, who has been in scintillating form since his £7.7million move to the club last year.
The forward has managed 47 goals in 65 games in all competitions, form which has understandably got Porto desperate to tie him down to a new deal.
However the 27-year-old – who previously admitted he hoped to get an opportunity at a bigger club in the near future – admits talks over a possible extension have broken down.
When asked whether his contract talks with the club had stopped, he told O Jogo: “Yes. The club has the issue – I will only give my maximum and not look to hasten things, because they will happen in due time.
“For now I do not feel the need to talk with FC Porto. I am calm.”
