Fulham are in talks with Bayern Munich about a potential deal for Joao Palhinha to join the German club.
The Portugal international, who will turn 29 next month, was targeted by Bayern last summer.
The two clubs were unable to agree a deal then but negotiations have resumed and Palhinha is keen to make the move.
He has made 68 Premier League appearances for the Whites since arriving from Sporting two years ago.
Fulham want close to £40m for Palhinha, having paid around £17m to bring him to west London.
The move could happen before the start of the Euros – despite Fulham boss Marco Silva predicting towards the end of last season that Palhinha would stay at Craven Cottage.
Speaking at a press conference last month, Silva said: “He’s been a key player for us. He was a player I really pushed to convince him to come to our football club.
“Last season he made a huge impact. This season, even after the situation in August and with all that noise, he was able to turn it around. Of course, he is a key player for us.
“Let’s hope he has a good tournament. Next season he is going to be here.”
