Casado is a left back for Sevilla and from what I have seen of him he looks pretty solid in that position. As for Kaladze, he is 29 years of age and is a Georgian international. AC signed him in 2001 for a fee of €16 million from Dinamo Kiev. He also looks to be a good player and in my opinion would be an ideal back up for our centre halves.
If Liverpool are to make a bid for both or either, the media are still unsure as to how much the players will cost The Reds'.
