Benitez admits "it's clear" Moores made a mistake selling the club to George Gillett and Tom Hicks. However, he admits current owners FSG now have the club fulfilling it's potential.
He told Four Four Two: "My memories of Liverpool are really good with (former owner) David Moores, but he couldn't spend the money to compete against the other teams.
"When he decided to sell, I think it was to the wrong people. It was very clear - I knew that and the fans knew that, then afterwards, was the proof.
"Now I think they have a model that is more competitive. They make the right decisions, which means they are able to compete with Manchester City."
Benitez also stands by his infamous "fact" rant he made in 2009 as the Reds lost the title to Manchester United by four points.
"People tried to compare that press conference to Kevin Keegan's (for Newcastle in 1996) but it was nothing like that. I was very calm.
"Everything I was saying was a fact, even though people were laughing about my way of pronouncing the word 'fact'. But it was very clear - if you analyse it now, I was right.
"Later on we went to Old Trafford and I remember a father and son had a banner saying 'Rafa's cracking up'. We beat United 4-1. In the last 11 games of the season, our only draw was the 4-4 draw with Arsenal, when Andrey Arshavin scored four goals. We won 10 out of 11.
"Manchester United had played in the Club World Cup and had a couple of games in hand. They won them and continued winning, but we continued winning as well.
"That's not cracking up. People have short memories. They follow the propaganda of the people who are winning."
