**One of the most formidable challenges in club rugby awaits Cardiff Blues in Dublin as the Welsh region attempt to end Leinster’s remarkable Guinness PRO14 unbeaten run.** The reigning champions have won 25 consecutive games in the Championship, with their last defeat in April 2019, and could set yet another record at the RDS Arena on Sunday. Leo Cullen’s men have a maximum 30 league points after six rounds and one more bonus-point win would equal the Championship record of seven five-point victories in succession. **What’s at stake?** For Leinster, a chance to write yet more Guinness PRO14 history - and cement their Conference A dominance - will be high on their priority list when they welcome John Mulvihill’s men. The Irish province are sitting pretty at the top of their conference with their perfect start to the 2020/21 campaign, holding a two-point advantage over last season’s runners-up Ulster. But they will not have it all their own way against the Blues, who are second in Conference B with three wins from six games - including a 22-5 victory over Benetton last time out.
