Colombia striker Jackson Martinez has raised alarms in the Premier League, after hinting that he is looking for his next challenge, according to ESPN.
West-London outfit Chelsea were previously linked with the Porto man in the summer, with Liverpool and Tottenham thought to be keeping an eye on the situation carefully.
The 28-year-old has managed to score a reputable 34 goals in just 40 appearances for the Portuguese side. In addition, Martinez played for Colombia against Belgium recently, a match which was seen by Chelsea manager Jose Mourinho.
Speaking with ESPN the forward was reported saying: "The years are passing and one day I hope to make a good transfer,
"It clearly depends on Porto, a club that sells its players so well.
"Leaving or staying depends on Porto but I will only go if there is something concrete."
Martinez is thought to be in favour of a switch to Chelsea, however it is unclear whether Mourinho is willing to meet the Colombian's €40m release clause.
After only appearing as a 71st minute substitute, it will be up to Mourinho whether he saw enough of the player to warrant such a transfer fee. However, with Demba Ba expected to leave for Turkey in January, a striker seems to be his priority.
The player is also thought to be on Borussia Dortmund and Napoli's radar.
