#1 Aaron Wan-Bissaka

Quietly, Aaron Wan-Bissaka's stocks have risen sharply in the past 12 months. He has been one of the best players for Roy Hodgson's Crystal Palace team this season, if not the best. He featured in 35 Premier League games this campaign, making 3.7 tackles and 2.4 interceptions per game.
He still needs to improve his ball distribution, but being only 21 years of age, he has time on his side. His strength is when he is called to defend in one-on-one situations, and no right-back in the Premier League is better than him in this department. His international call-up is not too far for sure.
He is a tailor-made for a club like Manchester United where full-backs are expected to cover the flank without showing signs of tiredness.
Manchester United are reportedly planning to make a £25 million bid for him but that should be rejected by the Eagles. Anything below £50 million will not be enough for Crystal Palace to sell one of their most prized assets.
