80m price tag aside, he is a decent defender and I'd give him a 6.5/10 this season. His defending isn't any improvement from Smalling at all to be very honest, and I am not quite impressed with his ball playing/distribution either, quite overrated in this aspect of his game in my opinion.
I am shocked some of you think he is one of our best player this season. He is average at best I think.
Anyway below is my rating of our player so far:
Rashford 8 - easily our best player/top scorer this season, he is becoming icon of the new Man Utd, showing flash of brilliance at times, need to improve his off ball movements and decision making though
Martial 8 - our most important player this season IMO, makes our attack play clicks in our team, hope he can stay injury-free though
AWB 8 - rock solid at the back, nothing go past him, weak going forward though
Mctominay 7.5 - our best midfielder this season, going to miss him alot in next 2-3 months
James 7.5 - our biggest surprise this season, very fast and unstoppable and full of positive play, needs to improve his finishing/end product abit
Greenwood 7 - our biggest hope, probably the best finisher at the club, impressive scoring stats for 18 year old, need more experience though
Williams 6.5 - always impress me whenever he plays, exciting young left back when going forward, still lack of experience though, not sure about how good he is at defending
Maguire 6.5 - solid overall, best CB in our team, he is abit of leader at the back, but his lack of pace and mobility has caused us problems at times
De Gea 6.5 - slight improvement from end of last season, make some good saves at times, but still prone to error occasionally which is abit worrying.
Lindelof 6 - overall did ok, his lack of ariel ability is quite worrying at times, but still he is our 2nd best CB in the team
Pogba 6 - Always injured, but has shown his quality with limited no. of minutes, our only midfielder who can create something from midfield
Fred 6 - Big improvements from last season, looks like starting to settle and find his feet, but jury still out for me
Young 5.5 - Well we still need to rely on him at times, I think he did his best with his age, can't complain too much
Shaw 5.5 - he is prone to injuries like every other seasons. He is not bad player though, but not our best left back anymore imo
Pereira 5.5 - he is definition of average player with right attitude in the game but lack of ability, and I just don't see it in him, but lately he becomes more productive and contribute more assists, let's see
Mata 5.5 - he is getting older and slower, but to break team sitting back against us, we probably need to play him
Tuanzebe 5 - not convinced yet although the potential is there, looks shaky at times, great at one moment but poor in the other, need to see more
Rojo 5 - well he is Rojo, you know what you get from him, typical south american defeder
Matic 4.5 - he is old and slow, but with both Mctominay and Pogba injured, we probably need to rely on him more
Jones 3.5 - He is a shite defender, we only play him when we need to rest others and do not want to win the games
Lingard 2 - By far our worst player and worst no.10 in the league, you just can't defend an attacker who scored 0 goals and 0 assists in whole year in AM position, he is definition of pointless player. He is good at pressing though, so he worths 2 points for me for this, and nothing else.
