Dave Ward believes stopping flankers Aaron Shingler and John Barclay is Harlequins' best bet of qualifying for the Amlin Cup.
Having seen their Heineken Cup hopes ended, barring a freak set of results this weekend, with last Saturday's 16-13 home defeat to Clermont Auvergne, Quins are in prime position for one of the second pool place slots which earns entry to the second tier Amlin Cup.
Standing in their way are Scarlets, who they must avoid losing to in Llanelli on Sunday. But hooker Ward knows it won't be easy against a side who got Quins' Heineken campaign off to a losing start with a 33-26 win at The Stoop back in October.
Ward said: “If we give them room to play they will destroy us. We need to close them down and get in their faces. They have got really dangerous backs and attritional forwards, so we need to get right into the scrum. Barclay and Shingler will want to play rugby, but they have three really talented backs too, so we have to stay focused across the park.
“We were really hurt by our performance against them at The Stoop, and putting that one right will give us a little bit of extra motivation. That game effectively ended our Heineken Cup hopes, although we can take a lot out of the way we fought back to take it this far.
“Everybody is now focused on getting an Amlin Cup place. We're looking to come back from Wales with four or five points. The boys still love talking about the big days they have had in the Amlin Cup, especially in Munster and Cardiff.”
Ward put in a man of the match display against Cleremont, which he hopes will give boss Conor O'Shea food for thought now Joe Gray is fit again and Rob Buchanan not far behind.
He added: “There is a massive battle foe the hookers' shirt now. All I wanted to do while the other two were injured was put my hand in, and I have done that. There are still areas of my game I need to improve, but Conor now has three strong hookers to choose from.”
