Henderson is hoping to emulate his pal during 2011-12 and add to the solitary England cap he gained against France last year.
He told liverpoolfc.tv: "Jack has come on massively in the past couple of years and done really well. He did really well on loan at Bolton and that gave him the confidence to go into the Arsenal team and do well.
"Hopefully I can come to this club and perform the same as he has. His success has given the rest of us from the U21s motivation to do the same."
