I think if we were even slightly more clinical not just in attack but also defence (by which I mean last ditch blocks, fantastic saves, etc.) we'd be winning the league comfortably.
I mean look at some of the games where we've dropped points - Chelsea - a 1v1 missed, Arsenal - a stupid individual error costing us the game, today. That's atleast 6 points dropped. Similarly, in CL - we finish the chances vs PSG, we're through. Ditto was the case last season as well, where in Pre-Bruno, we dropped way too many points because we missed our chances
