The Wales midfielder admits Gerrard couldn't do enough for him during his first days with the club.
Allen told liverpoolfc.com: "When I first signed here, he made a great effort to make me feel welcome and settle in - that says all about him as a person. He wants to help a lot of the younger players especially; we can all learn so much from him. Off the pitch, he's a great influence. He's our leader, he's our captain. When you see him play and you're playing alongside him, it helps to lift you that extra little bit."
