Full-backs:
Staying: Rafael, Chris Smalling
Leaving: Patrice Evra, Alexander Buttner
Coming in: Luke Shaw, Sead Kolašinac
With Patrice Evra likely to move on as his contract expires, United will be hoping to bring on board a new man that could make the spot his own for the next 10-15 years.
With the Frenchman tipped to be joining Inter Milan, United have made young Southampton full-back Luke Shaw their number one priority this summer, after he broke into the England team just in time for Brazil.
However, in recent days Schalke defender Sead Kolasinac has revealed that he has an offer on the table from the club, and is mulling over his best options before committing either way.
