O'Leary told the Daily Mail: "I read people now and they like Martin. He's media savvy and he's saying he's dealing with a young, small squad. Yet, when I said that it was 'Oh, he's making excuses'. I said the club needed investment to keep it alive. Why did Martin need £50 million this summer?
"At the end of the day, Martin, for all the money he has spent over three years - and they're raving about him - hasn't finished any higher than what I finished. Those are the facts."
O'Leary also said: "Some of things make me laugh. We had James Milner on loan for a year and they wouldn't give me £3m to buy him. Villa bought him for £12m eventually. Steve Sidwell was another, I wanted to buy him but was told we had young Steven Davis who was destined to play for Man Utd."
