#1 Axel Tuanzebe
He was Manchester United ever since he was an 8-year-old boy. Tuanzebe won the 'Jimmy Murphy Young Player of the Year' award in 2015. Even at 19, many in Manchester United believe he is matured as a player.
He has made excellent progress for a teenager at Manchester United. His reading of the game is so sharp, he rarely has to make sliding tackles. His pace and athleticism make his a good defender.
In his favourite position of centre-back, Tuanzebe has to compete with Eric Bailly, Phil Jones, Victor Lindelof, Chris Smalling, and Marcos Rojo. He can also play as a right-back or a holding midfielder but United is well stocked in all these positions.
He has made 4 appearances for United so far but everyone knows he is much better than that. One cannot fully blame Mourinho because he is under pressure to deliver titles and cannot risk with his starting eleven.
He is selected for the England u21 squad and Mourinho needs to outline a plan for him sooner rather than later or risk facing the story of Paul Pogba again.
