The club's director of rugby told Sky Sports News: "It's game-by-game at the moment. We're not going to talk about challenging for anything, it's game-by-game. We'll go to the bitter end and, if we play with an intent and intensity, we are a decent side.
"We've won 10 of 14 since our start so we're not rubbish. Our squad have been incredible, we've had to fight tooth and nail because of what we've been through injury-wise and are still going through.
"This squad is incredibly tight and they love a challenge. We've given ourselves a mountain but we're going to fight every single step of the way."
Quins face reigning champions Leicester Tigers next Friday.
