Lazio continue to put pressure on Porto for winger Cristian Sapunaru in a €12m swoop.
The Biancocelesti have been heavily linked with the 27-year-old Romanian already this week.
According to Portuguese newspaper A Bola, they are stepping up their efforts to sign the right winger this summer.
Porto have slapped a €12m price-tag on Sapunaru, but his own agent – Victor Becali – believes it can be lowered for a move to Serie A.
He helped Porto win the Europa League, Portuguese title, Cup and Super Cup this season.
