Harlequins coach John Kingston has warned his side against complacency when they take on London Irish at Twickenham on Saturday.
The Quins are currently at the top of the Aviva Premiership table, while the Exiles are 11th in the standings.
"We won't think that we will know and understand every week the key things we have to get right," he told the club's official website.
"We treat them the same as everyone we play, we don't judge or treat sides differently just because they have won or lost more games, we have to make sure we have everything we want in place.
"It's not about reflecting on how things are going for them or not going for them. They should have beaten us at the Madejski six weeks ago and they will know that. Expectation is a very dangerous thing."
Harlequins have picked up 37 points from 11 matches.
