Manchester United ended Arsenal's FA Cup hopes with an astonishing salvo that saw the league leaders fall apart at the seams as last year's finalists glittered. Wayne Rooney opened the scoring (16) before Darren Fletcher bundled home in the 20th minute. Nani capped a final individual display on 38 minutes before Fletcher grabbed his second. Lifeless Arsenal had Eboue sent off for an assault on Patrice Evra.
