Fulham have been alerted as Siriki Dembele has handed a transfer request in at Peterborough.
The Sun says the Ivory Coast-born winger, 24, has been attracting interest from a number of clubs, including Championship promotion hopefuls Watford and Bournemouth.
Premier League side Fulham have also been monitoring his progress this season.
Dembele has hit five goals in 19 appearances for the Posh this term, including a hat-trick in the 5-1 demolition of Shrewsbury on Halloween.
