Ricardo Carvalho arrived at Stamford Bridge in the summer of 2004, and went on to become an integral part of a squad which enjoyed one of the most successful periods in the club's history.
It soon became clear why Jose Mourinho - our manager at the time - had been so keen to bring his Portuguese compatriot to Stamford Bridge, as Carvalho, in combination with John Terry or William Gallas, formed a formidable defensive partnership which resulted in the Blues winning our first league title for 50 years in 2004/05, conceding just 15 goals along the way.
After a spell out of the side in 2005/06 he returned to the centre of a near impenetrable defence as we made it back-to-back league triumphs, even making a trademark break from the back to smash home as we sealed the championship with a 3-0 thumping of Manchester United at the Bridge.
The departure of William Gallas and injuries to Terry and goalkeeper Petr Cech brought even more responsibility on the Portuguese's shoulders during the next two campaigns, but he responded admirably and took the 2007/08 Players' Player of the Year award, before injuries hampered his involvement towards the end of his time at the club.
In total, Carvalho played 203+7 times for Chelsea, scoring 11 goals, and during his time at Stamford Bridge helped us to three Premier League titles, and he played a part in three triumphant FA Cup campaigns and two Carling Cups, before moving to Real Madrid in 2010.
