"I had been at Crewe all my life and I had no aspirations to leave because I had a really good job," Critchley told the Liverpool Echo.
"But when Liverpool comes calling it's very flattering. Alex Inglethorpe (under-21s coach) approached me initially and then I met with the manager. I didn't know either of them before.
"The fact that Brendan played a part in me coming here was a massive pull. I think it makes a real statement that Liverpool are willing to give someone like me an opportunity.
"I'm not an ex-Liverpool player, I'm not a name, I've got no international caps, but I do have years of coaching experience.
"When I first arrived Brendan invited me down to Melwood and I spent a few days watching training. To be alongside him, Colin Pascoe, Mike Marsh and John Achterberg was a great bedding in period for me.
"Brendan takes a massive interest in the Academy.
"He was here last week and knows all the players. He has great belief in the youth system and that gives us a better chance than most of getting players through."
