Details have now emerged that the Dutchman has a release clause in his current deal with Galatasaray, allowing the midfielder to leave the club should United activate it.
ESPN FC tweeted about the breaking news:
Sneijder and United have been regularly linked for many years now, but no deal has ever materialised, with the player ending up in Turkey after leaving Inter Milan.
ESPN FC reports that Galatasaray president Unal Aysal has confirmed Sneijder has the clause in his contract, as his club officially welcomed former Italy coach Cesare Prandelli as their new manager.
Aysal said, per ESPN FC:
Sneijder is a good player. We want to keep him at Galatasaray. If Galatasaray receive an offer of 20 million euros, we do not have the luxury of saying no. That is stipulated in the contract. All I can say is that if any club pays us 20 million euros and he wants to go, we can't force him to stay because it is written in the contract.
The Daily Mail's Luke Augustus recently reported Sneijder's thoughts about a possible move to join his international coach in the Premier League. He said:
I am happy at Galatasaray, I have established myself at the club and have settled in. However, if Van Gaal were to make me an offer, I would have to at least consider it. Nobody from the Netherlands can simply reject Van Gaal.
In the Netherlands, Van Gaal is something like the head teacher of a school. Not everyone is lucky enough to get into his good books. He trains his players very hard, and always expects the highest standards
The news is likely to alert United as they look to conclude their transfer business in good time, in preparation for Louis van Gaal's first season in charge at Old Trafford.
The experienced Dutch international has contributed to his country's efforts in Brazil, but he is not considered the world-class player of old.
Grant Wahl, senior writer for Sports Illustrated, highlighted this thought about the player during the Dutch team's last game:
Despite this, Sneijder has had a strong 12 months for club and country. During the season the flair midfielder hit a credible 13 goals in 35 domestic league and European matches, per WhoScored.com, and also has a goal and assist at the World Cup.
It is true to say he is not the player he once was, but he still offers a significant contribution to the teams he features for.
The fee of £20 million sounds a steep one for a player entering the veteran stage of his career, but as United look to add a number of quick fixes to their youth captures of Ander Herrera and Luke Shaw, Sneijder could prove to be the perfect addition.
Depending on which system Van Gaal decides to play, Sneijder could be used to complement United's strikers, especially if LvG does not fancy the talents of Shinji Kagawa or Juan Mata.
Ultimately, Sneijder would add experience and versatility to United's ranks, but he cannot be considered as a marquee signing in 2014.
