I think he is a terrible player. Granted he went through a bad injury, but Luke Shaw in 2020 is slow on the ball, doesn't offer anything going forward and his fitness and injury record is very poor. I'm not even sold on his defensive performance he just looks so lackadaisical and he rarely dominates opposing wingers.
Football has evolved, you need fullbacks to contribute going forward. He's got 1 goal and 9 assists across all competitions (PL, FA, EL, CL) in six seasons at Man Utd. That's basically a goal and 9 assists in over 9541 minutes or ~106 90-minute matches. He was the most expensive fullback at the time and someone we thought would dominate the flank, he's been disappointing. We went from Patrice Evra to this lard container.
