FC Twente defender Douglas claims to have no knowledge of a bid by Newcastle United.
The Brazil-born 24-year-old is closing on Dutch citizenship, which will make him even more appealing to potential suitors, because he would then be able to move to the Premier League without the need for a work permit.
Newcastle are aware of his situation and have had their sights on him for some time.
Douglas: "I and my agent know nothing of a bid from Newcastle.
"I want to stay at Twente this season."

Demba Ba's close range header has gave Newcastle a 1-0 half-time lead over Monaco in their friendly fixture on Monday night.
The Senegal international capitalised on hesitation in the Monaco defence midway through the half, and it was no more than the Magpies deserved, having carved out a number of good opportunities.
Shola Ameobi and Mehdi Abeid both threatened for Alan Pardew's side, but their French opponents went close too, with striker Ibrahima Toure a constant threat.
United should have been ahead inside 45 seconds. When Romain Amalfitano's corner wasn't cleared properly, Davide Santon collected the loose ball, strode forward and slipped it right into the path of Demba Ba.
The front man drove the ball across the danger zone and Shola Ameobi met it with an inventive back-heel, only to see his effort strike the foot of the post and rebound straight into the grateful keeper's arms.
Monaco's first chance arrived in the ninth minute courtesy of striker Toure. The dangerous forward connected with Nabil Dirar's corner from the right but, under pressure, could only volley well over the top.
The Magpies were soon back on the attack and Abeid flashed a left-footed strike from distance well off target, but they almost gifted their French opponents the opener.
Santon, playing at right-back, attempted to head the ball back to Steve Harper, but sold his keeper short, allowing Yannick Ferreira Carrasco to nip in. The left winger lobbed an effort over the on-rushing Harper but it dropped agonisingly inches the wrong side of the upright, much to Newcastle's relief.
Harper was then called upon to make an outstanding stop on 26 minutes, denying Toure from almost point-blank range. He didn't know too much about it, but the veteran's face was what prevented Toure from edging Monaco in front with a fierce shot from Carrasco's delivery.
But it was United who broke the deadlock in the 33rd minute through Ba. Danny Simpson's free-kick to the far post was headed across the face of goal by Mike Williamson, and when Monaco failed to clear their lines, Ba rose highest above keeper Daniel Subasic to nod in from a couple of yards.
With half-time approaching Toure was again Monaco's dangerman, nodding a corner down and wide, but Newcastle reached the break unscathed and could have been further in front, but Subasic denied Shola Ameobi after the big man had been fed by a great ball by brother Sammy.
Pardew made three changes at the break - James Perch went on for Mike Williamson, Haris Vuckic replaced Sammy Ameobi and James Tavernier replaced Mehdi Abeid for tactical changes.
Most of Monaco's best attacks in the first half came down the left and despite the new personnel for United, that was the case again. From a beautiful delivery, Germaine rose above Perch to send a powerful header off the angle of post and bar with Harper beaten for the first time tonight.
On 57mins Newcastle's fourth substitution, Ryan Taylor replaced Davide Santon, with the versatile Merseysider slotting in at right-back.
62mins: Both sides made triple substitutions, with Cheick Tiote, Dan Gosling and Gabriel Obertan on for Gael Bigirimana, Shola Ameobi and Romain Amalfitano from a Magpies perspective.
Jonas Gutierrez took the captain's armband from Ameobi, who started as skipper tonight.
78mins, Sylvain Marveaux came on for Demba Ba.
Good defending from Tavernier then leads to an attack as the youngster played a raking long ball for Obertan to race onto and the Frenchman had all the time in the world to size up a shot as he ran clear of the defence, only for his effort to be blocked. Following up is Gosling, but his goalbound effort is blocked on the line.
Steve Harper made another big save, this time to deny Valentin Eysseric from close range after slack defending from the Magpies.
That proves crucial as the whistle blew seconds later.
TOON FAN COMMENT: Sherwoodmag: "I watched the whole game on espn and it was a decent workout.Monaco are a few weeks ahead of us in terms of their pre-season and passed the ball well at times but although we didn't pull up any trees we looked comfortable.Late on Obertan looked a handfull up front but should have scored.
Vukic needs to work harder,he has the skill but shows no effort."
