Dutch international playmaker Sneijder - a long-term target for the Red Devils - has been linked with a potential switch Old Trafford on multiple occasions since compatriot Louis van Gaal was announced as the club's next permanent manager back in May.
The 30-year-old's obvious importance to current employers Galatasaray has previously been considered as a potential barrier to such a move, although president Unal Aysal has confirmed the value of the player's release clause and conceded that, while he hopes Sneijder stays in Turkey, the club are powerless to prevent him leaving if a team produces the appropriate fee.
"Wesley Sneijder has a release clause set at €20m [£16m]," he said. "Any team that give us that money and he wants to go, we can't keep him. Legally speaking, we have no right.
"I like this type of player, who have character and can be silent leaders, like Pirlo. I hope to have that kind of player this season."
Having joined Galatasaray from Serie A outfit Inter Milan last January, Sneijder made 28 appearances in the Süper Lig last season, netting 12 goals as Gala finished second to hated rivals Fenerbahçe.
If new manager Cesare Prandelli is to have a realistic chance of restoring the club to the top of the domestic standings, he will surely need to retain the Dutchman's influential services moving forward.

Manchester United move?
With the terms of any transfer now having been made abundantly clear by Prandelli himself, it remains to be seen if Manchester United and Van Gaal will be eager to pay what must be considered as a relatively modest fee for such a creative talent.
The club's midfield were subject to a barrage of criticism last season and Van Gaal - who, like Sneijder, has the small matter of a World Cup semi-final against Argentina to contend with at the Arena Corinthians in São Paulo on Wednesday night - will know that he will have to make further additions to further compliment the recent signing of Spaniard Ander Herrera.
In the case of Sneijder, Van Gaal will obviously have the considerable advantage of knowing every aspect of his game thanks to his experience as Netherlands coach.
Van Gaal decision
Sneijder, it is perhaps fair to say, is no longer quite the same caliber of player who was subject to glowing reports and appraisals during his heyday as one of European football's elite playmakers.
However, despite this, he is obviously still a force to be reckoned with and Van Gaal - using all his years of experience and achievement - will surely have to make a judgement call on just whether Sneijder is still capable of having the desired impact for a top club who are looking to swiftly return to prominence in the near future.
If he does indeed see significant merit in a summer pursuit of Sneijder, it does not appear that he would be particularly difficult or expensive to obtain.
