Which is a fair and balanced post.
Players who rely on pace in general do not develop the same technical ability when they are growing up because they do not need to, they use pace, a player with both is a rare breed.
Look at Sterling and Mahrez, Mahrez is technically brilliant, but he has not got Sterling's pace, so it becomes horses for courses. If Mahrez comes up against a defender who he cannot beat with his technical brilliance, Sterling may beat the defender with his pace and vice versa.
Walker and Cancelo are the same, Walker does not have the same technical ability as Cancelo, but he has pace and it is horses for courses for them if needed at RB.
Thats why i think the squad over the team is so important. You play the player who gives you most for that game.
Whatever happens Sterling will play 30 games, Mahrez will play 30 games, it is only a few who play almost every game.
