The Ecuador international has shone for Brighton since his arrival from Villarreal in 2022.
Estupinan now has less than two years to run on his current deal and talkSPORT says United have now opened talks with Brighton over his signing.
Also keen are AC Milan, with both fallen giants in need of a new left-back addition.
At United, there remains fitness concerns over Luke Shaw, while Milan have just sold Theo Hernandez to Al-Hilal.

I don't just understand this club anymore. we have Diego Leon ,luke Shaw and Dorgu. Even if we needed a new left back why didn't we exercise the buy-out option on carrecas of Benfica

Mention one of Man United's full backs that's better than Estupinan
Bro Man u entire squad ain’t good like this due to lack of winning mentality and the expectations people want from them, but still yet…. Estupinan isn’t the best choice for them.
