With Portuguese giants Porto and Benfica both keenly battling to sign him, Dalot joined Porto’s youth system in 2008 at the age of nine and has since blossomed into one of the most promising players in his homeland.

Such is the talented teenager’s undoubted ability, United manager Jose Mourinho has acted quickly in the summer window to secure the signature of his Portuguese compatriot, who becomes the club’s second signing of the summer after the capture of Brazilian midfielder Fred from Shakhtar Donetsk.

A typical modern full-back, the versatile 19-year-old is blessed with natural pace and an appetite to attack, has an excellent cross in his armoury and is comfortable operating at both right-back and left-back.

As well as being capable of dealing with opponents on the ground, Dalot is also a commanding six-footer and is equally adept at using his aerial presence to combat taller attackers.
