Dossena or Aurelio?

Now that Insua is off for some U20 South American championship, until Feb, Liverpool needs a leftback to replace that. Somehow, I think Insua have cemented his spot there, only after a few appearances. That's just how good he is. So now, Rafa decided to challenge both Dossena and Aurelio to win the battle for the vacant position. I wanted to laugh when I read that. After Dossena showed his speed-demon capabilities chasing down Mendy, Rafa still doesn't know who to choose? I bet even if Aurelio is better during training or whatever, the first choice will still be Dossena. Might as well ask Nazir to play seh. Hahah.
