Chelsea are on red alert over Porto striker Jackson Martinez's comments this week. The Colombia international is a top target for Chelsea boss Jose Mourinho, who wants to find a new striker signing in January.
"As the years go by, I have the expectation of one day achieving a good transfer. That obviously depends on the club and everyone knows that Porto will sell their best players. Staying or going depends on the decision of Porto," admitted Martinez.
A Bola says Chelsea are among a four-club race for the striker's signature, with AS Monaco, Borussia Dortmund and Napoli also keen.
