Valencia is kicking on and could do with competition in the full-back slot. The Reds will also welcome back Timothy Fosu-Mensah next month, when the Netherlands international returns from a season long loan at Crystal Palace.

Dalot becomes United’s second summer signing following the arrival of Fred from Shakhtar Donetsk yesterday.

And Jose Mourinho has expressed his delight at signing Dalot, who could be United’s right-back for many years to come.

“Diogo is an extremely talented young defender with all the qualities to quickly become a great player for this club,” he told the club’s official website.

“He has all the attributes that a full-back needs: physicality, tactical intelligence and technical quality, combined with a Porto Academy mentality which prepares players for the maturity they need at the professional level.

“In his age group, he is the best full-back in Europe and we all believe he has a bright future ahead of him at Manchester United.”
