The 22-year-old was at Anfield to watch Thursday night's Europa League win over FC Gomel and see at first hand the effect Brendan Rodgers has already had since he replaced Kenny Dalglish.
And having worked with the Northern Irishman in South Wales, he cannot wait to get started.
"To join back up with him was definitely a big pull for me," Allen told liverpoolfc.com.
"Brendan is so passionate about his football. He works day in, day out to improve the team and everyone individually.
"Everyone wants to work alongside someone who has that way about them.
"One of his best things is his man management. He commands the respect of everyone.
"I have a lot of faith that Brendan can bring success.
"I wanted to be part of this project and I've really got a good feeling this football club is going to go from strength to strength in the next couple of seasons."
He believes that grounding in the lower league will help him in the months that lie ahead.
"If you look at the amount of games I've played for someone my age, that would probably only happen at a team that's come through the leagues," he said.
"That experience has been vital for me.
"I blossomed and improved because of that and I wouldn't change it for the world.
"I feel proud. I am really thrilled and looking forward to my time here."
