Liverpool will reportedly have to fight off interest from Porto this summer if they hope to sign Jackson Martinez, as the Portuguese champions make advanced moves for the Colombian.
Martinez has a superb goalscoring record, having found the net 98 times in a combined 148 matches for Independiente Medellín and, latterly, Jaguares de Chiapas.
Liverpool have been linked with the 25-year-old for some time, and earlier reports in the Colombian press claimed the Anfield club had made a downpayment in order to secure Martinez's signature this summer.
However, it would appear this may not be the case and Liverpool may now miss out, with Porto now ramping up their attempts to lure Martinez to the Estadio do Dragao during the transfer window.
According to Portuguese newspaper Record, Porto hope to finalise a deal for Martinez in the next few weeks after formalising their interest in the forward, who has scored five goals in 13 appearances for Colombia.
