**Ospreys will be the latest side hoping to stop the juggernaut that is Leinster on Sunday afternoon, as the two clubs go toe to toe at the Liberty Stadium.** It is now 23 Guinness PRO14 victories in a row for Leo Cullen’s side, who haven’t tasted defeat in their last nine outings against Welsh opposition in the competition. The hosts will be looking to bounce back from a disappointing 23-17 defeat to Zebre last time out, but will be well aware of the challenge that they are up against, despite both sides missing a number of international players. **What's at stake?** The reigning champions have started this season exactly how they finished the last, with four bonus-point victories seeing them sitting high and handsome at the summit of Conference A, with a maximum 20 point return. Even with international players away, Leinster look able to beat any side in the competition almost at will, and they won’t be relenting on their charge on Sunday, with another victory in their eye line. Defeat to Zebre last time out will have hurt for Toby Booth’s side, who lost ground on the top two in the conference, but will be looking to put up a stoic performance to get back to winning ways. You have to go back to January for the last time the Welsh side lost two domestic games on the bounce, when they went down to Scarlets and Dragons either side of the new year. **What happened last time they met?** These two teams had polar opposite fortunes last season, with Leinster defeating all that came before them, while Ospreys finished a miserable campaign bottom of their conference with just two victories from 15 matches. You wouldn’t have guessed either team’s form if you watched the first half of the match from last season though, as the hosts turned the tables to go into the break 10-7 to the good. Tommy O’Brien had given Leinster the lead at the Liberty midway through the first half, only for Luke Price to convert a penalty, before converting Luke Morgan’s try on the stroke of half-time to give them the advantage. The visitors proved their Championship-winning mentality after the interval though, with Josh Murphy and Cian Kelleher going over to seal the victory. The win in Wales saw Leinster move 19 points clear at the top of Conference A, while Ospreys continued to be rooted to the bottom of the table.
