It is time to cease giving him some slack. It has been almost a year since he joined and he doesn't help himself in any meaningful way. It is not about the formation or the coach, he is simply inferior to our other midfielders even in the attacking aspect when he should excel the most.
At first, I still reserved my time to give him any judgement and I thought our lack of off-the-ball movement was the main cause of his dullness. But Barella managed to release Lukaku for Genoa's goal and he also launched a beautiful diagonal ball for Perisic which was tragically missed. Even Kolarov were still trying to make penetrative forward pass. And Eriksen? He preferred to make little neat touches here and there all over the pitch except the heart of defence which was his very role. There is no doubt about his skill with the ball. He managed to circulate the ball smoothly even on the tightest spot. But watching him is like watching circus player. Sure it was beautiful skill, but it is useless skill if it doesn't help us to score.
I understand goal scoring is not exactly his forte and his passing options are limited, but why don't you try shooting? Is he supposed to be good at shooting from distance? It is not about strategy anymore, it is about the will to make something happen. Look at Nainggolan. He looked out of depth and I despised his wayward long shot, but at least he showed he wanted to drag the team forward and it was more respectable than 60 minutes of rondo simulators.
If we want a midfielder to solely retain possession then Brozovic is better option than him. He is equally able at circulating the ball but he is stronger, runs further, defends better, and shots more dangerously. I would even prefer Brozovic's arm flailing because at least he cares if something goes wrong rather than Eriksen's non-urgent demeanor.
In short I do not really see Eriksen being better than our other midfielders. When physical midfielders like Barella, Vidal, and Brozovic are even more productive in creating scoring chances than our supposedly creative midfielder than something is terribly wrong. Eriksen may be the best ball playing midfielder that we have, but his attacking power is only as good as Gags and even the latter provides aerial threat through set pieces. So why would we pick Eriksen over other midfielders on our disposals?
