Harlequins head coach Conor O'Shea has admitted that he found little to enjoy during Friday's 22-19 victory over Worcester Warriors in the Aviva Premiership.
Nick Evans kicked over 17 points at Twickenham Stoop to keep Quins at the top of the table.
"There was just no flow, no momentum, no nothing in the game," O'Shea told Sky Sports News.
"It's a good lesson. We've won it and the guys dug themselves out but there's a lot of frustration in the way that game flowed.
"It wasn't a good game of rugby, not enjoyable but we'll take the four points."
Quins return to Heineken Cup action next Saturday when they travel to Italy to face Zebre.
