Jackson Martinez's agent Henrique Pompeo has hinted that Chelsea's interest in the striker may have more substance than envisaged, refusing to squash rumours of a possible move to Stamford Bridge in the near future. The Colombian striker has not had the best start to the season since moving to Spain from Porto, scoring only three goals in 12 appearances thus far.

The striker can be involved in a straight swap with Diego Costa, who has been in dismal form for the Blues this season. The Spaniard has managed only four goals thus far and a move back to Spain is something that the Daily Mail believes could well be on the cards. However, Chelsea, should they move for Martinez, will face competition from Tottenham, with the Evening Standard reporting that the north London club will also move for the forward.

"I can't say it's a lie, this is football and nobody knows what the future holds, what I can say is that Jackson isn't a player who leaves a club unless it's through the front door," Pompeo told AS, when asked about Chelsea's interest in the player.

However, he was quick to dispel any rumours about the player being unhappy at the club, stating that the decision to move to Spain was a well thought out one for which he has no regrets. Atletico are currently second in the league, two points ahead of Real Madrid and level on points with defending Champions Barcelona, albeit having played a game more.

"He made a decision and he's very happy in Madrid, he loves the club, although obviously he would have preferred to have got off to a different start on a personal level, but he's happy for the squad because things are going well. Jackson is very grateful to Atletico, to (chief executive Miguel Angel) Gil Marin and (president Enrique) Cerezo, because they made a big economic effort to sign him and with calm and continuity Jackson will pay them back on the pitch," Pompeo added.

Chelsea have been heavily linked with a move for a striker in January, with Jamie Vardy believed to be Guus Hiddink's top target in the upcoming transfer window. However, Leicester City manager Claudio Ranieri has refused to relent stating that he will do everything in his power to keep the 28-year-old at the club.
