It isn't just pace, he lacks agility and movements for the wing.
you can survive with lack of pace if you know when and where to move, when you know how to put the defender behind your back once you dribble past him.
Demir lacks a lot of intelligence in his game, not just pace.
This could very well translates in midfield as well, as he is required to have elite awareness in that position.
He feels like one of those kids who was too talented for their age group that they didn't feel the need to develop other areas of their game.
He has potential, and an elite one for sure, but the odds are usually not in favors of this type of players
Agree with this a lot. There are plenty of wingers that lack pace that get by fine because they are intelligent, know how to get a step on their man and receive the ball into a good position, eg Markel Suseata, Joaquin, Fekir etc are guys who succeeded in LaLiga without having blistering pace on the wing, being great playmakers who were able to stretch the field but they knew when to cut in and make runs. Plenty of players like that who are AM/winger hybrids and understand the positioning of that role and when to cut in.
But the problem is with Demir he looks like he has never played pro football before when he's on the wing. 0 runs in behind to stretch the defense, never takes on the fullback and when he does receive the ball goes inside and congests the midfield, laying it off to someone else. A player who is a good dribbler, and essentially, nothing else right now. Every time he receives the ball he cuts in, eventually Cadiz just started ignoring him because they may as well have not had a fullback there. 0 production down the right flank.
I want to see him in a game as CAM to see if he does any better but I wouldn't bet on it. He doesn't look atm like he has a creative eye, most of his touches are just layoffs and short passes. There is a good reason why we bought him for Barca B initially and why it's an buy option but Koeman's dogma and Laporta's shitty squad planning brought him into the first-team when he has almost nothing to offer.
