Rodgers, 36, quit Watford yesterday after just 192 days in charge to succeed Steve Coppell at the Madejski Stadium.
Rodgers said: "I spoke with Jose before coming here. He was great for me as he helped nurture my career. He's someone I can go to and get advice.
"When the approach came from Reading I spoke with him and he said 'go for it'.
"He knew Reading when they were in the Premier League. He remarked that the atmosphere at the stadium was fantastic."
