O’Driscoll returns for Dublin clash
History is also stacked against the Welsh in that, of the tournament’s 60 previous quarter-final ties, only 14 have produced away victories. Leinster include a fit-again Brian O’Driscoll for his first European start this term and have not lost a Heineken clash in Dublin for almost six years.
Aviva Premiership champions Saracens, meanwhile, face Clermont Auvergne in Sunday’s last quarter-final after Irish challengers Munster and Ulster have got to grips with each other at Thomond Park.
Saracens will face Leinster or the Blues at Twickenham on 29 April if they triumph, having reached the last eight as England’s solitary survivors.
