Ireland have named an unchanged line-up for a third successive match as they step up their RBS 6 Nations title bid against England on Saturday. Head coach Declan Kidney has retained the side that toppled France and Italy in the opening two rounds of the championship - victories that have planted Ireland at the top of the table. Paddy Wallace, who required stitches to an eye wound sustained against the Azzurri, has once again held off the challenge of Gordon D'Arcy at inside centre. The only change to the 22 comes on the bench where Mick O'Driscoll replaces Malcolm O'Kelly.
