#2. Trent-Alexander Arnold (Liverpool) - 20 years
Most people create their own opportunity, while others stumble upon it by chance or good fortune and the latter proved to be the case for Trent-Alexander Arnold, as he was the beneficiary of a long-term injury to then first choice right-back Nathaniel Clyne in the buildup to the commencement of the 2017/2018 season.
From then on, the Liverpool academy graduate did not look back, as he performed significantly well in Clyne's absence, so much so that when his more experienced teammate returned from injury and was unable to reclaim his shirt.
The 20-year-old has grown from strength to strength, making it to England's World Cup team, while also becoming an ever-present in Liverpool's new-look defense.
His displays this season have been so breathtaking that he has been identified as one of the best right-backs in the world at the moment, while he is also the forerunner to be named PFA Young Player of the Year.
