He needs to start adding more to the team. While he is a safe passer and technically sound, he is lacking in things to offer. He's currently at .3 key passes per 90 minutes, less than anyone in our entire midfield (including Song and Busquets). He hasn't dribbled or taken shots at all either. How he has been compared to Gundogan on this forum is beyond me.
In preseason, he showed a different side to himself. He'd carry the ball forward and play attack minded passes and be a genuine transitional or counterattacking threat. Now he's being way too safe and in that respect, not very useful. He doesn't "dictate" games, and now he's lacking in potency and edge as well. Hope he steps up because simply being able to make a bunch of 5 yard passes without much purpose or dominance is not the sign of an improving player.
