Irish international Alan Lee joined Norwich on loan from Crystal Palace on March 19th 2009 until the end of the 2008/9 season. He made his debut in the 1-1 draw at Birmingham on March 21st 2009 and was unlucky not to score

Alan began his career as a trainee with Aston Villa, turning professional in August 1995, although was never quite good enough for the first team at Villa Park. His league debut came after joining Torquay United on loan in November 1998, scoring 3 times in 9 games. In March 1999 he joined Port Vale on loan, leaving Villa in July that year when Burnley signed him for £200,000. He moved to Rotherham United for £150,000 in September 2000, scoring 36 times in 114 games for the Millmoor side. In August 2003 he moved to Cardiff City for a fee of £850,000, just days after impressing Cardiff manager Lennie Lawrence in a goalless draw on the opening day of the season

In January 2006, Lee joined Ipswich Town for £100,000. He scored his second career hat-trick in a 5–0 win against Luton Town on 29 October 2006. He signed a new contract at Ipswich until at least 2009 with the option of a third year. He moved to Crystal Palace in August 2008 after 103 games and 31 goals for the Tractor Boys.

Alan made 7 appearances for City scoring 2 goals. Despite City's relegation to League One, he has expressed an interest to stay at Carrow Road. Norwich and Palace were said to be in negotiations but could not find an agreeable price. In the meantime, it was reported by The Daily Mirror that Barnsley had made a bid for him.

Alan signed a two year contract with Lee Clark's Huddersfield, for an undisclosed fee, on 25th August 2010
