The England U21 international is enjoying the freedom that Holloway has granted him as he continues to gain first-team experience in the Championship.
Shelvey said: "I'm now playing in a role that I've played for England a few times and it suits me.
"You just roam about the pitch, try to get on the ball and make things happen.
"With my forward running, I think I can break and score goals. I proved that at Leeds, setting up the first goal and scoring a few as well. I like the position the manager has put me in.
"You always want more goals but I am happy with five in seven. I'm pleased with the way I've played in most games, but there have been a few when I've not been at the races.
