The midfielder has started six of our 13 games this season and been on the substitute's bench for the other seven.
It is a position he says he would have settled for at the end of last season but having been involved - he had a run of five starts and scored against Southampton in September - he certainly wants more.
Welsh international Simon, 22 last month, ran his socks off for the reserves on Monday night and now hopes to play a part in the big one against Leeds United at Elland Road on Sunday.
He reflected: "At the end of last season I said I would be happy if I was where I actually am now. But now I've played a couple of games I'm disappointed because I want more.
"I suppose that's natural. I want to be in the first team and playing regularly but I'm on the bench at the moment and doing the best when I get a chance. The more you get the more you want.
"The manager has told me to keep working and that I'm improving and you have to believe that. You have to keep working, keep your head down and take your chance when it comes along."
Simon Davies admits it's difficult to strike the balance between being happy to be on the fringe of the first team and the disappointment of not playing regularly.
