United and AC Milan are interested in the Ecuador international.
The Daily Mail says Brighton have informed intermediaries that Estupinan will be cleared to leave for an offer of £40m.
Both United and AC Milan are in the market for a new left-back and Estupinan fits the bill.
For his part, Estupinan favours remaining in England if he is to leave Falmer stadium this summer.
