Harlequins director of rugby Conor O'Shea has described his side's victory at Gloucester Rugby as "massive".
Quins made a return to winning ways in the Aviva Premiership on Friday as they came from behind to earn a 22-15 triumph at Kingsholm Stadium.
Nick Easter, Luke Wallace and Charlie Walker all touched down for the visitors, while Nick Evans added seven points with the boot.
"We were a bit frazzled and the first two penalties for 6-0 were not penalties and that is hard, because you go with a plan to defend the lineout and it was rubbish," O'Shea told BBC Sport. "That is difficult, but you know you are going to get decisions against you when you come here.
"It was a massive win for us. We knew we could have been out of it at 12-0, but we just kept playing around the corner of the loose position, which is our game."
Quins continue their Aviva Premiership campaign next Friday when they entertain Sale Sharks.
