The former Manchester City ace’s contract at the San Siro is due to expire at the end of the season, and the Rossoneri are desperate to ensure they don’t lose their man for free.
United were linked with a shock move for the 30-year-old over the summer, with Louis van Gaal known to be a fan of the rugged enforcer after coaching him in the Netherlands set-up.
The move fell through, but reports now suggest that the Red Devils could get their man before the end of the month.
The £10m fee mooted is likely to drop significantly given De Jong’s age and contractual situation, and LVG could use him as a short-term midfield fix – United currently lack an orthodox holding player.
Milan are keen to sell players to fund their own transfer plans, which may speed up proceedings.
