Fulham star Willian's agent, Kia Joorabchian, believes that his client is in demand this winter.
The Brazilian has restored his reputation within the Premier League after a poor spell at Arsenal.
The former Chelsea star has shone for Fulham this term, with the 34-year-old helping the Cottagers to a respectable top half position after promotion.
Joorabchian told talkSPORT: "I think 99% of people would have said that he [Willian] was finished when he left Arsenal: 'He's finished – he's done. His career is over.'
"Yesterday, we got a call from two top clubs.
“One said: 'This guy never ages.' The other said: 'He's like Peter Pan. How much would it cost to pull him out?' We said: 'It's not happening – he is staying at Fulham.'"
