Has looked pretty clumsy so far, which let's be honest is not exactly a great sign on a player in any position. I personally think this has to do with the way most teams set against us. They defend very deep and Nunez seems most at ease when running at defenders with space - you can clearly see he isn't comfortable picking the ball under pressure and with his back to goal or linking up play in tight spaces. It's just not the type of player he is. That was Bobby like 15 years ago.
Admittedly a bit worrying considering the team is creating absolute jack antimatter sh*t; he doesn't seem to be the type of player to create situations on his own, unlike say Diaz. But honestly- I don't think he was supposed to bring that type of contribution to the team, so it seems like an unfair standard to judge him by. I'd withhold judgement until he gets a decent run and we actually look even remotely decent in other areas of the field.
