He's a perfectionist. It's in his every move. Control is everything to him. From the way he moves, to the way he receives the ball, to how he scans the pitch, it's slowly becoming clear to me how much he needs information. Nothing must be left up to chance. Any alternative must be considered before making a decision.
So where does that leave him? For starters, he's not going to start making passes that has him the least bit uncomfortable. If he sees an opportunity opening up and it's not a sure thing, then we can be sure that he will second guess it four times over while scanning for alternatives before the window for that pass has closed.
The good thing, though, is that his comfort zone is clearly expanding. In the first few games he was like a nervous teenager trying to talk to his crush. Overthinking to a fault, playing it safe and ending up in the friendzone. Since then, he's led a stern venture into the unknown, step by step trying out new things and meticulously mapping down what works and what doesn't. Every game, he's a little more adventurous constantly building on what he learned the previous one.
Right now, you can see him beating himself up after messing up a pass. That sort of anxiety is symptomatic of something important, but it's not productive in itself. It only restricts, not allows. As he gets more comfortable, his confidence grows as will his perceived role in the team. He will learn that messing up is not the end of the world and that trying the right option is more important than succeeding in the wrong option.
