Manchester United have opened talks with Benfica for Ruben Dias.

Correio de Manha says United are in talks to sign Dias from Benfica.

It's suggested United are 'advancing' on the defender having watched him in pre-season for Benfica earlier this week.

Dias, 22, has a release clause of €66million and Benfica reportedly would not be willing to sell him for anything lower than that amount.

Real Madrid have also expressed an interest.
