This is what Rodgers had to say about the defense after the Balotelli-chat:

Just as some have been saying- there isn't a problem with the overall defensive organization, it's the one-on-one mistakes that we need to cut out. Lovren and Manquillo has shown they have the ability to minimise those mistakes- in fact I think we looked rather comfortable defensively in the first half against Southampton. We kept them at bay too easily and there was a marked contrast- for me at least- as opposed to last season. Once our intensity wore off, we started to look a bit rattled.
I have to say I disagree with that assessment. I also disagree with the way the video has been analyzed Daniel Rhodes on many of the goals.
To me the problem is mainly with the organization. Even by the standards of Rhodes, to concede 18 goals out of 50 due to organizational problems is actually a huge amount. That is close to half of the goals conceded!
The main issue for me is the way we set our backline to play off the ball. We do fine with the ball. As soon as we lose the ball our forwards press well (midfield can do better but are fine) but our defenders are so far away from midfield. Once the opposition breaks past that first wave of opposition, we have our defense retreating into our penalty box, waiting for our midfielders to track back.
A goal like the one scored by Stoke in part 2 is also a good example? Why are any of the defenders as well as Gerard and Henderson in the penalty area? Defensive line on the edge of the penalty area (where Henderson was), Gerard and Henderson plug the huge gap in the middle of the threading area. Mignolet sweeps any ball in behind the defense into the penalty area and problem solved.
The same with Charlie Adam's goal; Gerard loses the ball and Skrtel runs towards the penalty area. Go challenge Adam (he is not the most gifted technically). If he dummies you foul him just like Chelsea defenders do and problem solved. Going up to meet the opposition also gives your midfielders a chance to press from the back.
http://www.youtube.com/watch?v=-Cs0IemkVKsBarcelona were the best team during that time at pressing. Look at 1:36; Now that is exactly how our forwards and midfielders press for periods of any match. But our defenders are never THAT high at any period of a match (which they should). Puyol and Abidal are in Atletico's half, compared to our defensive line which is always in our half. We didn't see Puyol and Abidal sprint towards their penalty area and let the opposition come on to them.
http://www.youtube.com/watch?v=7ipiybRLqZcLook at Germany against Algeria. Germany also play a high line. Defenders are also on the midfield line and don't just sprint back to the penalty area. This is what prompts Algeria to play it long. And if it the ball drops in behind the defense? No problem, keeper is there to sweep. You see Suleimani in the first chance he is all alone but he has absolutely no chance to do anything with the ball. Neuer pushed to the side and he is the only Algerian player in their half. It looks dangerous, but its perfectly safe.
So in my humble opinion we can talk about Skrtel and Sahko making mistakes all we want but if we do not change the way we defense to suit our attack we will concede the a similar amount of goals no matter who is defending.
