Tottenham are considering a swap bid for Porto striker Jackson Martinez.

Spurs chairman Daniel Levy is ready to firm up his long-term interest in the Colombia international with a concrete offer this summer.

Superdeporte says Tottenham have already made an approach for Martinez and been quoted a €40 million price by Porto.

Levy regards the valuation as too steep, but hopes to drive down Porto's price by including Roberto Soldado in his offer.

Porto are open to the proposal, if Levy includes a €25 million cash component as part of the deal.
