Manchester City goalkeeper says he is proud to have caught the eye of Manchester United manager Sir Alex Ferguson prior to his move to the Etihad Stadium.
Ferguson admitted last month he had passed up the opportunity to sign Hart during his days at Shrewsbury Town, before signing for City in 2006.
The Scot called not signing the England international a mistake, praise that flatters the stopper.
“I wasn’t aware of that,” Hart told The Mirror. “The way I remember it was that no-one made a firm offer for me or showed any hard interest in me, until City came in.
“But it’s a great honour for someone like Sir Alex to have known who I was growing up. It makes me proud.”
In an interview with BBC Radio Five Live last month, Ferguson claimed he tried to sign Hart for £100,000.
"I could have bought Joe Hart for £100,000 so we all make mistakes," he said.
"I've no doubt [that Hart will be England goalkeeper for the next 10 years]. If you look at the England goalkeeper situation for the last 20 years, I would think he's easily the best."
After loan spells at Tranmere Rovers, Blackpool and Birmingham City, Hart was installed as City's No.1 at the start of last season, and claimed the Barclays Golden Glove after making 18 clean sheets in his first full season.
Hart was a non-playing member of England 2010 World Cup squad, but is now first-choice going into the summer's European Championships.
The 24-year-old already has 13 clean sheets to his name this season in the Premier League, and is likely to play a decisive role in City's attempts in claiming their first league title for 45 years.
