Benitez, who intends to sell Carson to Aston Villa, said: "I'm disappointed for Scott because he is a very good keeper.
"One mistake for a keeper is sometimes normal. I think he has quality and a strong mentality, so he will be ready for the next games and he will be really good because he is a good goalkeeper. He will be disappointed now but in a few days he will be ready for the battle. It will hurt but he needs to forget and think about the future."
