Mandaric appointed Holloway as the sixth manager of the Coca-Cola Championship club since April on Thursday night after prising him away from Plymouth and admitted he hoped he could forge as successful a partnership with him as he did with Redknapp at Portsmouth.
Mandaric said: "Ollie (Holloway) reminds me of Harry Redknapp. He loves the game, plays good football and has a great sense of humour.
"He is someone who I can talk to and is similar to me in that he can see an opportunity.
"Why did I leave Portsmouth? I didn't want to but I saw a great possibility at this great club and so has he." He continued: "It's been a hard and exhausting time for me up to this point but I feel now that I have got a load off my back and now I can breathe.
"We have got the right manager for this football club.
"I admire his honesty, his enthusiasm, his drive and he has the same ambitions that I have."
