#2 Right-Back
After the departure of Rafael da Silva, the pair of Antonio Valencia and Ashley Young has had to fill in the position for the club. Their inconsistency led to the buy of Matteo Darmian in 2015, who has been a complete disappointment. This season, in particular, the club has suffered due to the absence of a proper right back.
Valencia has had a nightmare season with him contributing to many losses at the beginning, before succumbing to an injury. It is understandable that the club decided against giving him a new contract.
Ashley Young is a versatile player, but at a club like Manchester United, he should be a back-up option instead of first-choice.
Diogo Dalot was brought in as an understudy to Valencia this season. In recent weeks, he has performed admirably, but his lack of experience in the Premier League will be an issue for United.
Aaron Wan-Bissaka has been a revelation this season at Crystal Palace. He is the only player in England to have completed 40 or more tackles and interceptions and to think he is only 21. With the right guidance, the duo of Wan-Bissaka and Dalot can cover the right-back position for a long time.
