#1 Samuel Umtiti

Samuel Umtiti has been a revelation for FC Barcelona in recent times and has solved their defensive problems that were so apparent last season. Umtiti is the quintessential modern defender, as he reads the game well and breaks attacks with his accurate positioning.
He does not make any rash challenges and safely thwarts away attacks due to his intelligent reading of the game. Umtiti is a young leader at Barcelona and his presence has had a huge influence on Gerrard Pique too, as the Spaniard has benefited whilst playing alongside a younger, more assured player.
He has a pass accuracy of 91%, an amazing statistic for a centre-half. Umtiti has also won 58% of his defensive duels and has been particularly impressive in headed duels. In aerial battles, Umtiti has a success rate of 67% and that would benefit him a lot whilst adapting to the nature of the Premier League. United would surely welcome an upgrade on Phil Jones and Chris Smalling and at 24 years of age, they will also get a long-term solution to their defensive issues.
Barcelona, however, will be reluctant to let go of such a talented player and hence it would require a whole lot of negotiations. The possibility of this deal taking place is still unknown but it might turn out to be one of the most interesting transfer sagas this summer.
