You're not the only one.
Gabriel has been our standout CB this season and its not even close.
A few weeks ago, a part of me started thinking, "maybe he's doing this shit on purpose to engineer a move to Real Madrid" ... I mean this use to be a tactic a few players in the past would employ to get moves to the club they actually "wanted".
Anyway, he's lucky his "complaceny" (you got it spot on) hasn't cost us any real points (at least I think so).
Thankfully, if he does go soon (which I hope he doesn't), thanks to Arteta's obsession, we've got quite a few players who can cover.
