The agents of Douglas insist they are not negotiating with Fulham and the defender is happy at Twente.
Reports last month suggested that Fulham and West Ham United had both made offers for the Brazilian defender, who can leave on a Bosman next summer, while Newcastle were also thought to have made a bid.
However Rodrigo da Silveira from MP9 Sports, who is the right hand man of Douglas' agent Marcos Paulo Ribeiro, insists they are not negotiating with the Cottagers.
He told Dutch paper De Telegraaf: "We are not in London and won't go to London. We are with Douglas in Enschede and are not negotiating with Fulham.
"On Thursday Douglas will play against Bursaspor. Douglas is very happy at FC Twente and wanted to remain there this season."
