Moussa Dembele has thrown his Fulham future into fresh doubt after switching agents ahead of the January window, Football Insider sources understand.

The French striker has ended his formal alliance with super agent Mino Raiola and is now represented by the brother of Manchester City midfielder Seko Fofana.

As revealed by Football Insider last month, Dembele has rejected the offer of a four-year contract by the Championship club to replace his existing agreement, which expires next summer.

This has alerted the 19-year-old’s admirers from the Premier League, who include Liverpool and Tottenham, and will ignite a January scramble for his services.

A source close to Dembele has told Football Insider that the brother of Fofana, who is on loan to French club Bastia after a spell at Craven Cottage last season, is taking care of the teenager’s day-to-day business.

The well connected Raiola, whose high-profile clients include Paul Pogba, Zlatan Ibrahimovic and Mario Balotelli, could still be used to broker any possible transfer.

Dembele, the namesake and former team-mate of Tottenham midfielder Mousa Dembele, has scored nine goals this season for manager-less Fulham, including six in the team’s last seven matches.

The France Under-20 international is regarded as Fulham’s prize asset and possessing similar potential to winger Patrick Roberts, who joined Manchester City in an £11million deal in July.

The Championship club are in a delicate position as they could receive only a paltry compensation fee if he leaves Craven Cottage at the end of the season.

Fulham would only recoup the £300,000 fee they paid for Dembele in 2012 if he moved overseas next summer but, were he to stay in England, they would be entitled to a far higher fee under Premier League rules.

Should the Londoners and the buying club from England not agree a fee, it would be settled by a tribunal, as in the case of Danny Ings when he joined Liverpool last summer after his Burnley contract had expired.

Dembele signed an initial three-year contract when he joined Fulham from Paris Saint-German. The deal was extended by a further 12 months last summer when both parties decided to trigger the option of a 12-month extension.

The centre-forward is now likely to be of serious interest to the Premier League big-hitters in the January window.
