FC Twente centre-back Douglas is seeking a move away from the Eredivisie and claims Newcastle United are one of several clubs interested in his signature.
Douglas, 24, has been at Twente since 2007, having signed from Joinville, but he now sees his future elsewhere, with both Chelsea and Tottenham reportedly joining Newcastle in monitoring the Brazilian.
"I have spent five years [at Twente] and have done my best for the club," he told NuSport. "I have won the title, the cup - it's time for a next step.
"I want to go abroad as I have outgrown the league. I noticed this year that I am sometimes a little too easy going down, then you make mistakes. I want to be tested every week.
"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."
