A naturally confident character, Shelvey comes from a family of West Ham supporters and spent a short time at their academy when he was 12.
He said: "I am excited about it. I supported West Ham as a boy but it is not easy to fill the boots of a player like Luis Suarez. I will just give it my best shot.
"I played against Young Boys in that role and I did all right. It is the same in any successful team. The goals have got to come from all over."
