The Gers will commence their post-split fixtures by making the short trip to Lanarkshire as they look to maintain their unbeaten campaign in all competitions.
Speaking to RangersTV ahead of the clash, the goalkeeper said: “As a Rangers player, the Old Firm matches are the games that you look at and look forward to.
“We’re all excited to step onto the pitch and hopefully produce a positive result.
“I suppose I’m one of the more senior players in the squad now. I think we have such a range of senior players, mixed with young players who are full of energy, so we’ve got a good balance.
“I think everyone is experienced enough now in this fixture to go and play.
“I think it’s the same mentality for every game. It’s 11v11 at the end of the day, and it’s fine that we’re away from home.
“We know Celtic’s qualities, but we know that we can match them and hopefully we can come away with the three points.
“We’ve played them multiple times this season and we’ve had positive results. By no means does it signal that we’re going to go and beat them this time; we know that they’re a good team.
“We need to be on our game on Sunday and hopefully we will be.”
Ten league games remain for Jo Potter’s side, all against top six sides, as they sit atop the ScottishPower Women’s Premier League.
There is also plenty to look forward to with a Sky Sports Cup final and a Scottish Cup semi-final looming on the horizon, although Fife insists the side’s full focus is on the immediate challenge of Sunday.
She added: “We’ve got really tough fixtures coming up and there are no easy games. Every team can take points off each other, and we need to be switched on for every game.
“We have the Old Firm this week then we have a cup final.
“It’s really, really competitive, and you can see in the table that it’s so tight. It’s going to be a really tough run-in for every team in the top six, so we need to be ready for the challenge.
“We don’t think about it too much, to be honest. It’s one game at a time and, don’t get us wrong, we’re delighted to be unbeaten, but it’s in the past now.
“Hopefully we’re able to end the season with a title, but there’s still a long way to go.
“We’re still in every competition. We have a final to look forward to, and a semi-final in the Scottish Cup. But we’re focused on this game at the weekend first and foremost.”
