Anthony Wordsworth spoke to iFollow Blues ahead of facing Yeovil Town in the Emirates FA Cup this weekend.
The Blues midfielder is hoping he can recover from a calf injury to play in the First Round at Huish Park.
And after two wins in two games, Wordsworth is confident that Blues will approach the game against the League Two outfit in a professional manner.
“We’ve only conceded one in three games. As a team we’ve defended better and our mentality has changed.
“We need to go there thinking, obviously, about winning the game, no matter that they’re in League Two.
“We need to show them why they’re in League Two and why we’re in League One. We’re a better team so we need to prove that.
“The belief has changed when we go in front. I know it’s only three games. The Peterborough one was hard to take because it was a sloppy goal.
“To go two clean sheets after that I think our belief has changed. Once we get in front, the last couple of games I didn’t feel like we were every going to get beat.”
On his injury, Wordsworth added: “I’m fine. After five minutes on Saturday I got a tight calf, I managed to stay on the pitch but I probably haven’t done myself any favours.
“Everyone was telling me to come off, but I’ve been injured for a while and I didn’t want to. When you miss so much football you want to stay on the pitch.
“Hopefully I’ll be alright for Saturday.”
Even as he prepares to play in the First Round, Wordsworth says he’s hoping to draw one of the big teams in the Third Round.
“It’s another important game that we want to do well in. We want to try to get to the Third Round and draw one of the big boys.
“All the players look forward to the FA Cup growing up watching it and they have the show on BBC One where they show all the games, so all the boys will be trying to get on the scoresheet to pop up on the telly.
“Growing up being an Arsenal, I remember Arsenal always doing well in the FA Cup. I’ve not really had a great run as a professional. I think I’ve been knocked out in the first round pretty much every time. Hopefully that can change on Saturday.”
