That's quite harsh considering there are plenty of good things that he does. His ball carrying is good, and when he's fully fit/confident his dribbling is very effective. He is very reliant on making late decisions when running with the ball, so when he's not in rhythm his output can be lacking. He has good passing and control for a wf.
His left foot is often a wand too! He can bend it in, cross with curl, hang/float it with backspin etc.
not too bad at all
His
assists per 90 are in the 99th percentile for wingers and forwards in the top five leagues, a number backed up by his Expected Assists (xA) per 90, which are in the 77th percentile.

It's not as if he's not had big moments against the best teams either tbh.
