Fulham fans are tiring of the 19-year-old forward, who is reportedly still in Tottenham's radar.
The north London side rate the teenage talent highly but face competition from Benfica.
Tottenham are said to have nearly signed Demebele in January, meanwhile, and could land the youngster over the summer as he is out of contract at Craven Cottage at the end of this season.
But is that necessarily the best thing for Spurs?
Indeed, the north London side certainly need a back-up forward and recent weeks have shown they could have even done with one in January.
Fulham fans, however, have slammed the 19-year-old's attitude following their 2-1 loss to Bristol City. They feel Dembele is far from giving his all with his mind distracted due to the uncertainty over his future.
And the Fulham forward has been accused of turning up for 20 minutes then going home... Should Tottenham perceive that as a warning?
Another apology to the supporters due from Luke Garbutt. And don't get me started on Mousa Dembele who contributes about 20 minutes a game— Tony Watts (@Tonywauk) March 12, 2016
I would drop Dembele for next week. Attitude and desire not there. Cauley, for all his faults, runs channels and moves into space #ffc— Harry Simmonds (@supersimmo123) March 12, 2016
If Dembele starts at Birmingham next week something's wrong. No time for his attitude today. Jokanovic should have dubbed him off earlier.— Chris Gilbertson (@ChrisGilbertson) March 12, 2016
I'm glad people are now seeing that dembele isn't that good...been saying it a long time...all the hype for an average player #ffc— Adam Wilson (@sargeyboy24) March 12, 2016
You will do well to find a player in world football who is more overrated than Moussa Dembele. How on earth #THFC want him I'll never know— DJP (@DP_FFC) March 12, 2016
Woodrow needs to come in for Dembele who seems uninterested and thinking about his big money summer move. No reason to keep playing him #ffc— kelvin clark (@fulhamkelv) March 12, 2016
