#1 Aaron Wan-Bissaka (Crystal Palace)
Aaron Wan-Bissaka has been a sensation since making his debut for Crystal Palace in 2017. He was an ever-present figure in the Premier League for Roy Hodgson's side this season, missing only three matches (hamstring strain).
Wan-Bissaka proved instrumental down the right-hand side for the Eagles, though their lack of progression is a worry - he's likely to consider his options and want a step-up in quality soon, despite committing the immediate future to staying in south London. Naturally, his impressive displays have not gone unnoticed and he has been linked with many of Europe's elite, including Borussia Dortmund and United themselves.
Wan-Bissaka posted impressive statistics this season, averaging 3.7 tackles, 3.7 clearances and 2.4 interceptions per game. He created chances galore, though a lowly four assists doesn't do his creativity justice after an excellent season. His workrate, speed and technical ability fit the United mould perfectly, though he will not come cheap - not least given his superior defensive qualities.
