Fulham and Sporting CP are locked in talks for fullback Miguel Lopes.
The defender was linked with Tottenham earlier this summer.
Record says Fulham have offered €1 million for Lopes, whose camp are pushing the Championship club to up their contract proposal.
Fulham's offer is for €1 million for a 12-month loan, with a €5 million option to sign Lopes permanently.
The Cottagers are also willing to pay a percentage of Kostas Mitroglou's salary at Sporting following his move from London.
