#3 Wilfred Ndidi
Wilfred Ndidi has been exceptional for Leicester City this season as he has helped them out defensively a lot more than any other player in the Leicester team. He is second in the league for tackles behind Everton's Idrissa Gueye and has a very remarkable success rate of 70%.
With Leicester building a young squad with a very impressive midfield trio of Maddison, Tielemans and Ndidi, it may be hard to get the Nigerian international from the Foxes for cheap, but if they do manage, it will be a very good investment for Manchester United.
Still only 22, it may cost United upwards of £50 million to get him to the Theater of Dreams but given Nemanja Matic's current form, they can't afford to take risks with the Serbian slowing down pretty evidently and help shore up United's midfield which has been struggling off late.
