The agent of Porto striker Lisandro Lopez says he will move abroad - possibly to England - next season.
Fernando Hidalgo said: "He has a year left on his contract and this is the right time to try and sign him, partly because there is no possibility of a renewal at Porto.
"It's time for new challenges and we're already deepening contacts with a Spanish team and an English one."
Lopez has been linked with Aston Villa and Newcastle United this season.
