The 24-year-old Brazilian is keen on leaving Holland this summer in order to play in a tougher league.
“I have personally been in touch with Ajax and immediately said that I’m not interested,” he told NuSport.
“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.
“I have spent five years [at Twente] and have done my best for the club.
“I have won the title, the cup – it’s time for a next step.
“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 has also been linked with the likes of Chelsea and Tottenham.
