Kaladze had a brilliant season, often playing CB but also LB in 2004-05, the year we lost the CL final to Liverpool. If I remember well Nesta and Stam missed several games, Maldini has an injury near the end of the season, and Billy was already very old, and Kaladze stepped up big time -- he played more often than Stam that season.
He was also our starting LB in the 2002 Champions League winning team, and indeed he was a decent DM early on too, though we were pretty poor at the time as a team.
A very capable, versatile player and a good servant overall IMO.
He did become very bad later on as CB also got a lot stick from fans. I always thought his form collapse coincided with the murder of his brother, after a long kidnapping situation; the stuff of nightmares. Maybe it's just coincidence, but the timing does match. He also had quite a bit of injuries.
