If people read that interview Rodgers did, he doesn't once mention Agger, he says he knows his qualities and then goes on to explain fairly honestly why he felt we needed a bit more leadership/presence in there. Everyone said he made a scapegoat of Skrtel last year and that his days were numbered (when he said he felt we needed to be more vocal), look at him now.
And a point that's been conveniently missed is that he played yesterday. I bet there's no one interviewing Rodgers today asking why he chose to play Agger instead of Toure/Sakho. And if he came out with a response about wanting a bit more elegance in there or whatever, I'm sure that would be equally turned against someone.
