Jamal Lewis says Norwich City's players control their individual and collective destiny when they visit Chelsea on Wednesday night (7:45pm).
The Canaries head to Stamford Bridge for the Emirates FA Cup third round replay, having previously held the Premier League champions to a 0-0 draw at Carrow Road.
Speaking to the media on Tuesday afternoon, the Academy graduate said: "You can't be a negative thinker.
"There's definitely a chance for us to win. If you tell yourself it will happen, it happens.
"I think I've used all my nerves now. First impressions are over so it's time for me to play with confidence and passion.
"I want to embrace every moment of it. I pride myself on doing my job for the team.
"We need to be good in our box and good in their box. We won't show them too much respect."
Lewis' career pathway hasn't always been a guaranteed one, having also excelled in sports away from the football pitch.
"I've been doing athletics alongside football my whole life," he explained.
"I took a break from football to focus on athletics but when the call from Norwich came, it was a no-brainer. The athleticism helps my game, especially in the latter stages.
"I feel like I can outrun any player I'm up against. Converting from left-wing to full back was tough, but it's becoming second nature.
"I've learned a lot from this manager and want to repay him for giving me the opportunity. I've waited for it a long time."
