As I said weeks ago, when playing at his full potential, he's better than Evra.
Evra had better leadership (though it's something he grew into over the years, and I feel the same is happening now with Shaw, who leads by example and the team knows they can trust him to receive any ball they pass him and retain possession and build attacks). Evra also had more flair on the ball, but I feel Luke is a far more effective ball carrier with his power, pace, and uncanny ability to use his first touch to propel a surging run forward into space.
Shaw has also become insanely accurate and consistent with his final ball, which was perhaps Evra's one glaring weak point throughout his career.
