"When I was there it was Abramovich's first year," Ranieri went on. "Everything was well and I got on very well with him.
"But now it's four years on and I don't know how much enthusiasm he still has for football and how much money he still wants to spend.
"I know he wants to take Chelsea to the top but it depends if he's still willing to spend more money.
"I'm very proud of my third season where we did well without spending a single pound. That year we came fourth in the Premier League and also got into the Champions League.
"And you have to remember, Chelsea were a failing team before.
"But the following year was something that will stay with me all my life. My last year was something that will never be repeated.
"It was like fantasy football! I was like, 'I'll take this one and that one...and that one'. It was amazing."
