Goalkeeper Carlo Nash signed for Norwich City on 10th July 2013. He was a free agent having been released by Stoke City at the end of the 2012/13 season. He is expected to be third choice keeper at Norwich, replacing Jed Steer who joined Aston Villa.

Bolton-born Nash began his playing career at Manchester United but gave up football at the age of 14 to concentrate on his education. He played for non-League Rossendale United and Clitheroe with whom he played in the final of the FA Vase at Wembley Stadium losing 3–0 to Brigg Town. This led to a £35,000 transfer to Crystal Palace in 1996 for whom he made 21 appearances.

He joined Stockport in 1998, making 89 appearances and had a short spell on loan to Wolves. He moved to Manchester City on a four and a half year deal in January 2001 which cost City £100,000. He made 38 appearances for City but once Manchester City were established as a Premier League team, Nash was sold on to Middlesbrough for a nominal fee in August 2003.

After only playing five games for the club in two years, he moved down a division to join Preston North End on a three-and-a-half-year contract in March 2005. He set a club record of 24 clean sheets with Preston during the 2005–06 season but wished to move on stating that the club's ambitions did not match his own. He was linked with a £500,000 switch to Fulham in January 2007 which was rejected and he was dropped to the bench.

Nash joined Wigan Athletic on a month long emergency loan in February 2007, due to injuries to their first and second choice keepers. Wigan signed him permanently for a fee of £300,000 on 27th June 2007.

On 4th March 2008, Stoke City signed Nash on an emergency loan deal for the remainder of the 2007–08 season following Márton Fülöp's recall to Sunderland. Nash played a vital part in Stoke's promotion to the Premier League with a penalty save against Watford and a number of important saves on the final day of the season against Leicester City. He had made 10 appearances for Stoke.

Nash moved to Everton, the team he supported as a boy, as reserve goalkeeper to Tim Howard on a two-year contract in September 2008. Following Nash's release from Everton he returned to Stoke after signing a one-year contract in July 2010

Nash is an enthusiastic travel photographer in his spare time, and set up a travel book publishing company called 'Luxury Backpackers'. Nash is a devout Christian and said in an interview with the Church Times, "I find that being a Christian helps me to deal with disappointing moments in football a lot better".

Nash was released by City at the end of the 2013/14 season

In January 2015, it was speculated that Nash would be joining Tony Pulis' coaching team at West Bromwich Albion.

In July 2016, he joined Oldham Athletic as goalkeeping coach. He left Oldham in 2018 to join former Preston Teammate Graham Alexander at Salford City. He took up the same role at Port Vale in July 2022. He left Port Vale in February 2024.
