#3 Trent Alexander-Arnold (Liverpool)
Trent Alexander-Arnold is a 20-year-old right-back who plays for Liverpool in the Premier League. He has also featured for England's national team, having made five appearances since his debut in June 2018. A-A was included in England's World Cup squad this summer, too.
A-A has been with Liverpool since the start of his career, having made his way through their youth system. Since being promoted to the first team in the summer of 2016, A-A has consolidated his position at right-back, ousting Nathaniel Clyne (who has recently been shipped out to Bournemouth) and making the role his own.
With a market value of around £40m, there's no doubting that Trent Alexander-Arnold is on course to become one of the best right-backs in the Premier League.
