One major thing that he contributes with is having a player that can actually strike the ball properly. You probably need to not feel so much pressure, having a lot of training session where you succeed behind you and having the confidence to know that you would succeed at a pretty frequent rate; in order to start contributing at a high level with assists and goals. Doku, Savinho and Bobb are not doing it yet, but doing it at training, getting into good positions and let the instincts take over should improve the output given time. O. Marmoush does not have those problems. He can strike the ball - it is more an issue of settling into the team and the league.
