The former Arsenal star has stated that Sir Alex Ferguson wanted him at Old Trafford.
The retired French midfielder was part of the Arsenal side that won the Premier League title in 1997-98 but opted to leave the Gunners and move to Barcelona.
Upon his return to English football, the silky deep-lying playmaker decided to sign for Chelsea.
However, Petit has revealed that Manchester United wanted to convince him to move to Old Trafford, with the legendary Scottish manger having plans for the Frenchman in his midfield.
Petit concedes that he made a mistake in choosing to return to London, with the allure of living in the capital a reason behind his switch to Stamford Bridge.
"I made a lifestyle choice to the detriment of the sporting choice," he told football365.fr.
"And on the rare occasions that I've made that choice, I've got it wrong. It was the same thing when I left Barcelona to go back to Chelsea.
"I gave priority to the social life in London when [Sir Alex] Ferguson expected me to sign for Manchester United.
"My wife didn't want to go to Manchester. I'm really annoyed at myself - I should have insisted upon my decision.”
Petit spent three years at Chelsea before retiring but ironically did not win any silverware during his time with the West London club.
Although the 44-year-old was a World Cup winner with France in 1998, his club career should have heralded much more success given his talents as a player.
During Petit’s time at Chelsea, United won the Premier League and an FA Cup crown.
