FC Twente defender Douglas has revealed that Newcastle United are not the 'biggest club' that are interested in his signature.
The 24-year-old Brazilian has been on the Magpies' radar for the last six months and recently hinted that he is seeking a move away from Holland this summer.
However, Douglas has refused to be drawn on where he intends to go.
He said: "Five clubs are interested and there's a bigger club than Newcastle.
"I cannot still say anything about it but I hope soon to have my new club."
Douglas made 41 appearances for Twente last season, scoring five goals.
