The 21-year-old has been a revelation since joining the Hoops from Fulham for just £400,000 18 months ago and a number of Europe’s top clubs are keen with the likes of Real Madrid, Paris Saint-Germain and Barcelona all said to be keen.
Dembele has been battling hamstring issues this season but has still managed to chip in with eight goals, and now reports claim Brighton boss Chris Hughton would like him on board at the Amex Stadium.
Celtic will be keen to keep hold after qualifying to play Europa League football after Christmas and are likely to knock back any bids of £20million as £30million is the reported valuation but it remains to be seen if the Seagulls will go that high.
Meanwhile, Dembele could hold out for a move to a bigger club if he does leave Parkhead.
Watford boss Javi Gracia does not think Abdoulaye Doucoure's form will be affected by his omission from France's latest squad.
