I genuinely think that's really harsh/based on a pre-conceived idea which you won't allow to be changed.
Since getting thrashed by Spurs we've conceded 11 goals in our last 10 league games, that really isn't a bad record at all. For context it's better than Arsenal (14), Chelsea (16) and even the all singing all dancing Nuno's wonderboys from Wolves (14). It's the same amount as Spurs themselves, and only 1 more than City. Our record over the course of the season has been fairly consistent in that regard too, with only the period immediately preceding and including that Spurs game - where we conceded 11 in 3 games - ruining what would otherwise be a pretty excellent defensive record. We've had problems from set pieces yes, but overall our defence really hasn't been that bad.
When you get into the realms of talking about what might have happened if a player wasn't where he was supposed to be, and another player had fouled someone when they didn't in order to make a point, I think it's reasonable to say that you may not be looking at things very objectively.
