He has all of the raw material to become a top winger but there is something else going on mentally that he needs to overcome. Not sure if it’s a lack of confidence or nervousness, or even overthinking everything, but he needs to be played into form and has to get minutes. However the desire and effort needs to be there and at the moment it is lacking.
Everything else is coachable and there are some very simple things he can do to make himself a more effective asset to the team. Get a yard of space and put a ball in the box. Quicker passing and more one twos. More sprinting and closing down. More yards covered. All of these things help the team, which is the first aim. Play yourself and the team into form and don’t rely on others to bail you out.
The pre-requisites of being a winger are all the same no matter who you play for. It’s a tough position where you get found out easily for not doing the absolute basics. A few examples; Track back and help your full back. Press the opposition full back and stop the ball from going down the byline and force it inside. Pass the ball at a basic level. Take on your opponent when one on one. If you aren’t doing these things well, then it’s very difficult for the manager to like you, even if you are as talented as Dibling.
