From watching him from a few games, I can see his passion, he is always committed to everything he does, he's willing to fight for the team, something which many players don't have.
Technically, I've seen very little of him, whether that be a lack of service or not playing on the shoulder of the last man. I think it's too early to judge a player, but I noticed that he wasn't fluently interchanging with the front 3 today as you highlighted.
In short, he's not even played a handful of games, give him time.
