We changed the team to bring Cissoko and Johnson in. It didnt have an adverse effect there, because they're better players than the ones they replaced.
The system (a system I prefer) dictated who went where. Johnson, as is Johnson is a better attacking defender, than a defending defender and to be fair, a wing back position has been discussed may times for him. On the other side, Enrique is the same, yet can have more errant defencive displays, hard to believe, but he does and the recruitment of Cissoko is a massive uplift compared to Enrique.
One being an uplift in ability, the other playing in a position thats suits his abilities better.
Should be the same with Agger and Skrtel.
Agger has his foibles, but in terms of that sweeper role in a back 3 he's so much more suited to it than Skrtel that it's not even a competition. Agger should be in there no questions asked because he's the only CB we have who can maximise the role and step out of defence to a decent degree.
No questioins asked, really? You'd be happy to put Agger in there even if he was playing bad?
Our back 3 with Skrtel, Kolo and Sakho is a massive uplift in our defencive capabilities. Agger can fit in there as well, of course, but the two new additions and system change, for me, are more to do with what we had previously - which was a footballing back four, as opposed to a defencive back four. Enrique, Johnson, Agger are all players more comfortable with the ball at their feet, than defending it. Skrtel and Carragher were the does what it says on the tin, types.
So we bring in new players, change the system and look and feel more capable of defending against teams. Lest we forget last seasons Achilles heel and the reasons why, and to be fair to Rodgers - he's addressed the issue.
Skrtel currently finds himself in the team and he's in the team on merit and I believe, that whilst Rodgers will ask the back three to play the ball out, he predominantly wants a mobile solid defencive unit. Which currently, we have, so should we really start changing because we 'think' another player will do a better job, when as we stand right now, as a unit they are playing very well.
They have slip ups, but who doesn't, and the more they play together, the more the issues can be ironed out, and if not, then we can make a change, but we have to give the back 3 time to settle, or are we to make changes every time a player doesn't have a perfect game?
Skrtel shouldnt be playing that role over Agger, not at all. If he's playing too well to be dropped, as in your opinion seems to be the case, then Agger should still come in but Skrtel should push out Toure or Sakho.
You seem to be advocating the reinstatement of Agger regardless. That is unhealthy for the team and the squad and you do a disservice to those players currently holding those positions.
Players earn their place in this team, not due to misguided loyalty and as I've said before - that should go for everyone, regardless.
