Sorry to bring this up again but Felipe is ALL left foot, not compatible with Giorgio. I think Agger can use his right more than just walk on it so I wouldn't say no to him from what I read about him.
I should rephrase: Agger will only want to leave if he loses his place.
I don't know how willing Liverpool will be to sell.
This will probably be the last season in which Hyypia plays regularly, so Liverpool my be reluctant to sell him. I'm not sure when Agger's contract runs out, though.
