i agree that Carragher will start as long as he is fit but i dont think Carragher is a better player than Cahill. He is a better defender but Cahill is a more all rounded player which is what we need. Better with his feet, quicker, scores more goals, more of a threat in the penalty box.
But carragher is a legend and i will be happy for Cahill to learn from him what it means to play for this club.
