Portsmouth are believed to be interested in signing Porto forward Lisandro Lopez.
Lopez is regarded as one of the best strikers in Europe following his goalscoring exploits for Porto.
The Argentine international is top scorer in Portugal's SuperLiga and his performances have caught the eye of a number of clubs.
Lopez's agent, Fernando Hidalgo has claimed that Portsmouth and Sevilla are battling it out to sign the South American.
Pompey boss Harry Redknapp is likely to have substantial funds to spend this summer as he looks to build on their fine season this term and he could make a move for Lopez.
However, Porto are reluctant to let Lopez go with the club insisting their star striker is not for sale.
