Portuguese right-back Diogo Dalot, 19, will have a medical at Manchester United this week before joining the club from Porto.

Diogo Dalot could become Jose Mourinho’s first summer signing after Manchester United opened talks with Porto over a £17.5 million deal for the Portugal Under-21 right back.
