Raheem Sterling is Gareth Southgate's go-to left winger. Though he has been out of form this season, it is understandable given his past form for England, especially at the 2020 European Championship.
Alongside Bukayo Saka and Harry Kane, Sterling is part of England's first-choice attacking trio, reducing Marcus Rashford to a role off the bench. The Manchester United forward has been in good form this season and deserves his place in the squad, but it's understandable why he is being used primarily as a substitute given the pace he brings to the game late on against tired legs.
However, what many England fans can't understand is why when Rashford has been brought on he has been deployed on the right-hand side of the attack.
