Quins led the league for much of the current season, but a drop in form in recent weeks has seen the champions slip to third.
The centre told Sky Sports News: "It's always important to get a bit of momentum at this stage of the season.
"Obviously you want to win every game, but it's a tough old league and we are just taking each game as it comes, put our game on the field and let the rest take care of itself.
"Once you win a trophy at any level, you want to keep winning trophies. As a team you want to win as much as you can so, as a team, we are determined to defend our title."
