For all we know, this could be Rodgers warning Agger that if "you don't want to accept / negotiate with us, you can leave". Or a situation like that.*
*Where Agger wants large wages that we cannot afford.
I mean, Agger IS a fan of the club. He has stated that he will never play for another team in the same league (so if anything, he's off to Spain) and has been with us through the dark times. He loves the club, and always gives it his all. Our defence is MUCH better with him in the squad (you can see the difference when he doesn't play) and suits the philosophy better than any of our other defenders. I highly doubt this transfer is forcing him to leave or anything relating to get rid.
Regarding Rodgers quotes, could this not also go to other players in the squad? If the right price comes in, you're out. It's a warning to all players, not just Agger. Imo anyway.
