He's good but too inconsistent and generally not as productive in terms of goals + assists but that could be due to how we set-up.
He's not really a winger imo. I'd rather see him as a CAM or mezzala. He has the attributes and strengths for it. His decision making is strange around the box sometimes, but it seems better when he's playing more centrally.
This season he's struggled quite a bit after starting the season in excellent form, and looking like he was going to be a big part of creating chances for Ronaldo.
But last year, his production was excellent. He had 5 goals-6 assists in 1062 minutes. That's under 100 minutes / goal or assist.

And Cuadrado too imo. You can't be as versatile as he is and be totally brainless. He just isn't a good finisher and sometimes lacks the ability to deliver the final ball.
It's usually not his brain that lets him down around the box, but his poor technique on his final ball. He has terrible aim shooting most often, and he has a tendency to overhit crosses when he's not in form. But usually he shoots when you would want a player to shoot and crosses when you'd want a player to cross.
