The 29-year-old's contract is running down, and even triggering an extension to take it beyond 2019 would make him available for a meagre £25m next year.
Alderweireld's deal expires in 2019, and while the club can extend it by 12 months, it also contains a £25 million release clause that can be activated next summer as long as there are at least two weeks remaining in the transfer window.
United and Barcelona have been following Alderwiereld's situation for some time, particularly after Manchester City seemingly dropped out of the race by signing Aymeric Laporte.
The 29-year-old centre back is proven as one of the Premier League's most dependable defenders and his contract situation will no doubt mean there are a host of suitors, both from England and overseas, who will be looking to capitalise on an exit which seems more and more likely every day.

Alderweireld would be a strong addition to any of the sides interested in him, and his loss would be a significant blow to Spurs.
