Well, that, and that every single team(except us) shoots wide or straight at your gk when ever they are inside your box, no joke.
And to be serious, just explaining your defensive stats down to plain luck makes more sense than anything else, you concede big chances every game.
Now, your team will suffer defensively with Messi next season, but honestly, you wouldnt have conceded much more this season with him in this team than not, because again, there is this "aura" surrounding you domestically.
Cant wait until Xavi is gone, none here may like him, because he makes the team play "bad", but its better to be lucky than to be good.
Just get a coach that can concede goals against non-RM teams, will you? Thanks.
