No - He's creating chances for himself. It's inarguable that he gets a lot of shots away, and often from good positions that he's got himself into.They're paying some otherwise unemployable university graduate to massage Klopp's ego by telling him Dortmund weren't playing shite but unlucky in his last season. We've scored 36 against the coach wreckers 22, that's the only metric that matters. If Nunez is creating a huge number of chances that are being spurned by Klopp's hoofers, perhaps he moved to the wrong team.
He appears not to have the technique to make the most of this skill, but then he also seems to take a lot of difficult to control first time hits. Not sure if xG takes into account how hard the technique is, as he could be boosting his xG further by taking on shots that even the best players would avoid.
One curious aspect is that his impressive goal scoring record last season was based on massively outperforming his xG. Perhaps he is one of those comic characters that discovers magic boots in a dump, but then loses them.
