Man calm down. Shaw barrely played for Man Utd in the last two years and he arrived as a 19 year old boy, which 19 year old has more than 88 in SM? Moreno is 25 and he played first team for Sevilla and Liverpool for the last 4 years, of course he will have higher rating. If Shaw is better he will show that in an upcoming season, but u cant expect him to rise while he was injured.
