#4 Squad overhaul
As we have seen throughout the majority of the season, through injuries and players underperforming, Manchester United are in dire need of a squad overhaul.
Players like Chris Smalling, Luke Shaw and Wayne Rooney are rumoured to leaving, while Zlatan Ibrahimovic's and Michael Carrick’s contracts might not be renewed and Real Madrid might come in for David De Gea.
In truth, Mourinho needs to recruit a new right back, centre back, Carrick’s replacement, winger and a centre forward. Whether they bring in all of those players is a different story, but they need to pad the squad out and bring in quality too.
For the position of right back, Manchester United do not need a starting player - they already have the amazing Antonio Valencia. However, they do need a backup defender that is comfortable there. Timothy Fosu-Mensah might have been substituted there, but, typically, he is a midfielder.
