Smith could make his debut today against Manchester City and said: "I've got to show that I can move up to the Premier League on a permanent basis.
"I believe in my ability and I think I can do that, given the chance.
"It's a great club here and I know I will have to work my way into the side. I certainly don't think I'm going to come here and play every game straight away - I'm not that big a name.
"So I know I have to get my head down, work hard and try to prove I am worth a starting place.
"I've never played in a team that has been overly successful at this level, so it would be nice to be in a team that can compete a bit more."
