He said: "I'm excited to be back in the game, I'm excited to be with Worcester Warriors Rugby Club and I'm looking forward to what is a huge challenge.
"Right from the outset to come back into rugby was about finding something that did excite me. In my own head I got to a place where I thought I was going to carry on with TV.
"I didn't really see a challenge that lit the fire back inside and I think conversations with Cecil was something that started to do that.
"The opportunity here to restructure how the club goes forward was almost a challenge that, if I didn't do it, would eat me away further down the line."
Warriors finished the 2012/13 campaign in 11th position in the Aviva Premiership after recording five wins.
And Ryan admits he has a lot of work ahead of him before the club can become more competitve in the top-flight.
He added: "I don't think there's a simple answer otherwise it would have been found before and it would be naïve to think there is. It is about breaking a cycle of operating in that bottom three or four clubs.
"I'm not naïve enough to throw things around and think I'm going to come in here with a magic wand. We've got to restructure the club so that as it goes forward over the years it starts to get the benefits of certain things that have been put in place."
