Manchester United are in talks to sign Porto full-back Diogo Dalot, Sky sources understand.
Jose Mourinho has reportedly been in the market for a right-back to compete with Antonio Valencia for a place in United’s starting line-up, with Matteo Darmian’s future at the club unclear.
Portugal U21 international Dalot is understood to have a €20m (£17.4m) release clause in his Porto contract – which expires next summer – and is thought to have attracted interest from some of Europe’s leading clubs.
The 19-year-old, who made his first-team Porto debut in February, could now depart the Estadio Dragao to link up with compatriot and former Porto boss Mourinho.
Dalot played out of position for Porto at left-back in the Champions League knockout stages against Liverpool earlier this season.
He is a product of Porto’s academy and won the U17 Euros with Portugal in 2016.
