The Welsh outfit have yet to open their account in three matches in England's top flight but the former Watford man is confident after an improved showing in the 0-0 draw against Sunderland on the weekend.
"I'm frustrated and pleased in a way. In terms of performance, it was a lot better and we got at them and created more chances," he told the South Wales Evening Post.
"The first couple of games we didn't create much but we got at the heart of Sunderland and should have won the game.
"But you've got to put the ball in the net and, as a team, we haven't done that yet. But I'm a confident guy - the goals will come."
He added: "We've got two clean sheets, which means the defenders are doing their jobs. It's up to us forward players to get a goal and that will release a bit of tension."
