If he doesn't play next season (which appears highly likely) his value will drop well below what it is now. So if Rodgers knows he isn't going to be involved then getting the best price for him now is just common sense if you ask me. He will have seen enough of him already to know whether or not he is going to fit into his plans. I can't think of 1 top four team in Europe who have a centre forward as one dimensional as Carroll. Money wasted aside, and for purely footballing reasons selling him is absolutely the right thing to do.
