I've heard that Nunez is all the rage (haven't seen him) so bit surprised to hear that. Know a few Gooners that want Nunez here.
I don't think he's struggling per se, has 16 goal involvements from 27 games. He's not been prolific in front of goal but his assist numbers are good. I think he'd suit the PL. Expensive though and he'd need to improve in front of goal.
