It's very easy to go through goals we've conceded to give examples. I did it with the goals we've conceded in games we've lost, unsurprisingly the thread went very quiet because no one wanted to admit Koulibaly might just not be able to help as much as they're saying he would. A few days later and we're back to unsubstantiated rhetoric to hammer our own players and promote a new signing. Koulibaly is a great player but he simply can't have the impact some are suggesting, he's being made out to be a god like figure who never makes a mistake, plays out of defence better than Beckenbauer and yesterday one poster even said that he's our only chance of winning all 4 competitions. Despite no player in history ever having done so, people are just getting carried away with a very good player and think he's magically going to solve all our defensive issues, defensive issues which cannot be solved by one man, no matter how good he is.
