The Dutch defender, who was available on a Bosman free transfer, has signed a three year deal at St Andrew's after successfully completing a medical on Friday.
Melchiot's signing brings the number of new signings at Blues to four following the signings of Emile Heskey, Muzzy Izzet and Julian Gray earlier in the summer.
Manager Steve Bruce is still hopeful that his fifth target, Jesper Gronkjaer, will join Blues despite claims from Sevilla that he will move to Spain to join them.Mario Melchiot Information Date of birth 4 November 1976 Height 5.8 Place of birth Amsterdam Weight 11.6 Nationality Dutch Position Defence Recent Career History By Club (1999 onwards) Team Debut Apps (+ sub) Goals Yellows Reds Chelsea 22/04/2000 148 (16) 5 14 2 Recent Career History By Season (1999 onwards) Season First App. Apps (+ sub) Goals Yellows Reds 2003/2004 23/08/2003 29 (4) 2 4 0 2002/2003 23/08/2002 36 (4) 0 3 0 2001/2002 19/08/2001 47 (3) 2 5 2 2000/2001 13/08/2000 31 (4) 1 2 0 1999/2000 22/04/2000 5 (1) 0 0 0 Appearances 148 (+ 16 as sub); Goals 5; Yellow cards 14; Red cards 2
