Atletico Madrid have rejected a €30m (£22.8m, $32.6m) bid from Tottenham Hotspur to secure the services of Jackson Martinez, according to Marca. The Colombia international has also been linked with Chelsea after struggling to adapt to La Liga, but the Spanish publication says that Diego Simeone's side are not ready to sell for less than the €35m they paid Porto for his signature last summer.

The 29-year-old striker was one of the hottest prospects on the market last summer, having garnered a reputation as one of the most clinical forwards around after netting 92 goals in 133 appearances for Porto.

Arsenal, Liverpool, Tottenham and AC Milan were all linked with his services, but Atletico beat them all after agreeing to meet his release clause, following the departure of Mario Mandzukic to Juventus.

Martinez, however, has failed to replicate his form at the Vicente Calderon, having scored just three goals in the opening part of the season.

The Mirror reported last month that both Chelsea and Tottenham were considering to taking advantage of the player's struggles in La Liga to secure his services in the current January mercato.

His agent, Henrique Pompeo, did not dismiss the speculation when asked by AS about the Blues' interest in the player. "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," he said, also dispelling rumours about the player being unhappy at Atletico.

Marca now reports Spurs recently took matters to the next step by launching a official bid of €30m to lure him to White Hart Lane. Atletico, however, immediately turned down the proposal from North London as they consider the sum not enough for a player who cost them €5m more just months ago.

Mauricio Pochettino has not hide the fact he is keen on signing a striker to ease the load on Harry Kane should a good opportunity arrives. Nevertheless, it looks the Argentine will need to look somewhere else or increase his for the Colombian.
