With Dan Agger and Martin Skrtel now nearing match fitness, Benitez could soon have four senior centre-backs to choose from - not that he's complaining.
"It will be good for us to have Skrtel and Agger available again because at the moment we have only Sami and Carra," the Spaniard told liverpoolfc.tv.
"It is important to have two players for every position.
"It was also good for us to see (Harry) Kewell and (Xabi) Alonso because we know that they have quality. It was important for them and it was important for us."
