Manchester United have agreed a fee with Porto for Diego Dalot and arranged a medical for later on this week, according to Sky Sports.
Sky Sports report that an undisclosed fee has been agreed between the two clubs for the 19-year-old full-back, who is understood to have a £17.4m release clause in his contract with the Portuguese giants.
They go on to say that a medical is now set to take place later on in the week ahead of a move to Old Trafford for the teenager, who only made his first-team debut in February.
Dalot is a right-back by trade, making him an ideal replacement for Antonio Valencia next season but can also play at left-back if needed, which may also see him fill in for Ashley Young at times in 2018/19.
For a side such as Manchester United, with their very reasonable title ambitions, to be going into yet another season with wingers Antonio Valencia and Ashley Young, left over from the Sir Alex Ferguson era converted into their first-choice full-backs would just not be acceptable.
Dalot is raw and his purchase is an uncharacteristic risk on a young player from Mourinho and the hope is that he actually plays him; either in his preferred right-back role or as the makeshift left-back he can be, and doesn’t hoard him as a another young player to sell on for a profit.
If he can use his younger legs to scamper up and down the right for United, delivering quality from wide areas and enabling Mourinho to drag his defence higher up the pitch, then he will be worth every penny.
