Harlequins director of rugby Conor O'Shea wants more from club's squad after their narrow 16-14 victory over Sale Sharks on Saturday night.
Sale were by far the better side in the first half but failed to capitalise on a number of chances and only lead 7-3 at the break, courtesy of Dan Baird's try.
Quins hit back in the second half through a Tim Visser try and a Nick Evans penalty, but were fortunate to hang on for the win after a missed penalty and a drop goal from Sale fly-half Danny Cipriani.
O'Shea doesn't believe their performance will intimidate their Premiership rivals, admitting they were lucky to claim an unglamourous win at Twickenham Stoop.
"We've started the season well but tonight was not a performance we can be proud of at all," O'Shea told Sky Sports.
"I don't care about winning and losing and I never have – I care about the way you play and the energy you bring. For 20 minutes in the second half we did well to get a 16-7 lead but then we let it go.
"We said before the game we wanted to show people what we're about and there won't be too many people afraid.
"We've got a win which we potentially didn't deserve, but I know where we're at as a team because of how well we've played over the last few weeks."
