The energetic left back made his full debut for Palace, aged 17, against Watford in October 2007.
Lee was educated at Whitgift School in South Croydon and joined the Wimbledon academy at the age of nine.
Five years later he left for Arsenal but the move didn't work out, paving the way for him to join Palace.
Lee gets up and down the pitch well to support the attack and can also play at centre back. His defending has also improved since his arrival at the club and he is one of the fittest players in the squad.
His first team value was underlined on January 8 2008 when he signed his first professional contract for a period of two-and-a-half years.
