**Leinster may have wrapped up a third straight Guinness PRO14 title on Saturday evening, but they do not have too much time to bask in the glory.** This week they must turn their attentions to Saturday’s crunch European Champions Cup quarter-final against Saracens - a match which pits last season’s finalists against one another. Leinster head coach Leo Cullen, however, insisted his side [must take time to enjoy their Guinness PRO14 hat-trick](http://www.irishtimes.com/sport/rugby/pro14/subdued-celebrations-for-leinster-as-saracens-move-into-focus-1.4353710) before focusing on their next test. “The big focus is enjoying the moment and then turn the page,” Cullen said. “It’s important to savour the moment and not look too far ahead now. “In terms of a plan for next week, we’ve already discussed it as coaches. We had a previous plan for Saracens and the personnel has changed over the course of five, six months, but we’ll put a plan together. “But at the moment it’s about enjoying each other’s company in the dressing-room.” Saturday’s beaten Finalists, Ulster, are also in the last eight and travel to Toulouse on Sunday. Fly-half Ian Madigan insisted after the weekend’s defeat that his side can put their disappointment behind them and [deliver a performance to remember](http://www.newsletter.co.uk/sport/rugby-union/dan-mcfarland-bemoans-ulsters-costly-errors-2970166). “We can regroup, there are massive positives to take,” Madigan said. “In the midfield, I thought Stuart McCloskey and James Hume were phenomenal. “Any time Mike Lowry and Rob Lyttle got the ball in wide areas they looked dangerous and Jacob (Stockdale) was quality in the air. “It wasn’t our night but we know we can take positives from it, go to France and win.” In addition to the Champions Cup contests, there are three Guinness PRO14 sides in European Challenge Cup quarter-final action this weekend. First up, on Friday, Dragons make the short trip over the border to English Premiership high-flyers Bristol Bears. Dragons flanker Taine Basham is likely to play a key role and his confidence would have received a boost if he picked up The Rugby Paper on Sunday, with Basham identified as one of four players Wales legend Shane Williams would like to see make [an international bow in the inaugural Autumn Nations Cup](http://www.walesonline.co.uk/sport/rugby/rugby-news/four-new-wales-rugby-players-18927104). Saturday sees both Edinburgh and Scarlets cross the channel as they take on Bordeaux-Begles and RC Toulon respectively. And Edinburgh full-back Blair Kinghorn is desperate for his side to finally show what they can do in knockout rugby as they go in search of silverware. The Guinness PRO14 Semi-Final defeat against Ulster, which saw Edinburgh let a 19-7 lead slip, was the latest in a string of frustrating defeats for Richard Cockerill’s side in recent years. “We’ve had Munster in a (Guinness PRO14) quarter-final and lost that, Cardiff in the Challenge Cup and lost that, Munster again (in the Champions Cup) and then Ulster,” [the 23-year-old told The Offside Line](http://www.theoffsideline.com/blair-kinghorn-edinburgh-2/?v=79cba1185463). “So we’re getting ourselves into the positions and then not executing to get us to that next stage. “But I have full confidence in the team that we have the ability to do this. It’s just a bit frustrating that we’re not, but I think you’ll see when we play Bordeaux that we’re ready to. I think the game against Ulster will be the final turning point, that everything will click and you’ll see us in action on the big stage. “I think if you were at the review on Wednesday, you would be like, ‘Right, we don’t want to be here again, we don’t want to be in this moment again where we’re getting shouted at and we’re hawking the same things that we’ve been through for the last four years’. “I think everyone’s sick and tired of it. We’ve got to the point where I just feel like we’ve turned a corner.” Scarlets, meanwhile, were beaten by Toulon in two tight Pool games earlier in the competition but centre Steff Hughes believes his side have what it takes to turn the tables this weekend. “We know what we are going to be up against, they are a powerful team across the board with a huge pack,” [Hughes told the Scarlets club website](http://www.scarlets.wales/article/steff-hughes-relishing-toulon-challenge/). “When we played them out here at Parc y Scarlets in January (a 27-15 defeat), I think the conditions suited them a little bit more than us that night. “We know we have to be disciplined in the tackle area and not give away too many penalties and also maintain the intensity of the game in order for us to play the way we want to play. “It is also important that we control the game and play in the right parts of the field. It should be a great game and occasion. We’re really looking forward to the challenge.”
