The 26-year-old shot-stopper has moved to Ashton Gate after being released by the Welsh side in May and also seeing a potential move to Watford fall through
Tom Heaton has signed a one-year deal with Bristol City, after rejecting interest from Watford.
The ex-Manchester United trainee suffered a frustrating campaign with Cardiff City last season, playing second fiddle to David Marshall for the majority of the season, making only 10 appearances.
Despite this, his season will be remembered by many due to his League Cup heroics in penalty shoot-outs, against Crystal Palace in the semi-final and again at Wembley against Liverpool.
Heaton has now revealed that the staff at Bristol City were the key factor in the move, although he admitted he had come close to a transfer to Watford, now managed by Chelsea legend Gianfranco Zola.
"I met the manager and the goalkeeping coach at the end of last season and I took a shine to them," he told BBC Radio Bristol.
"It looked as if I was going to Watford for a time but from the moment I came through the door here it felt great."
The goalkeeper also added that he is keen to play regularly and is hoping he can make a name for himself at Ashton Gate.
"The desire to play is what drives me," he said.
"I could have stayed at Cardiff but it's not what I wanted to do,
"I wanted to establish myself and hopefully I can do that here."
