Ranieri took the Juve job in 2007.
“I will reveal some behind the scenes information about the summer of 2007," Ranieri told Calcio 2000.
“In any case, I will say it honestly, I'd have been happy to go back to the Premier League. It would've been my first option."
Ranieri was sacked by Juve in May 2009 with two rounds to go in the Serie A season, having taken them to third in his first campaign.
“We did very well in my view with more highs than lows. A few rather irritating complications arose. I had some problems with the then-director general. I left because when you make decisions like that, you make them with extreme conviction.
“The blame for the transfer market strategy was attributed solely and exclusively to me, but the decisions were made by three people: myself and director of sport (Alessio) Secco for sporting matters, while the economic issues were down to (director general Jean-Claude) Blanc."
